Analysis Flexibility
No two applications are the same and so a variety
of physisorption measurement types are included
to optimize data point spacing in the measured iso -
therm according to pore size and pore volume.
And since some users prefer the classical helium
void volume method and others helium-free analyses,
both techniques are at the disposal of the operator.
Advanced analytical techniques that require scanning
the isotherm hysteresis loop, or pore size distribution
of thin films using krypton gas, or the largest available
library of density functional theory (DFT ) calcula-
tions, are accommodated as standard features.
Customizable for H igher Throughput
By offering 2- and 3-station versions, the Autosorb iQ
represents a huge improvement in sample throughput.
This is most evident when properly analyzing micro-
porous materials in detail. These notoriously slow
measurements (because of restricted diffusion of gases
at the very low pressures required for analysis) have, in
the past, been the cause of many laboratory bottle
necks. Simultaneous analysis of up to three samples,
each using their own dedicated sets of pressure trans-
ducers, effectively triples throughput and capacity
without sacrificing the quality of the results. For
busy industrial labs doing high throughput surface
area and mesopore analyses, the economic benefits of
the increased capacity are dramatic. Even the chemi-
sorption models are available with up to three physi-
sorption stations.
Superior Performance For Today, Combined With Future Flexibility
Operator Convenience
All instrument operations are accessed through the
Windows®-based software program. Fully custom-
izable analysis parameters can be set up ahead of
time and recalled as often as one likes. So too can
degassing protocols. Reconfiguring the instrument,
between physisorption and chemisorption modes,
takes mere seconds. The unit is sized to comfortably
fit on a standard laboratory bench with all electrical
and gas connections to the side, rather than to the
rear, for easier access. An optional rolling cart is available
if greater mobility is desired or bench space is limited.
Technical Excellence
Electronic pressure transducers form the core of the
instrument; among them, ceramic diaphragm capaci-
tance types offer superior stability at lower pressures.
The high vacuum system of the MP and XR micropore/
chemisorption models is mounted internally and
features a 90,000 rpm turbo-molecular pump backed
by a dry diaphragm pump
‡. A constant, small cold zone
(physisorption mode) is achieved by using the proven
coolant level sensing system. Interruptions to the
analysis are minimized by virtue of a dedicated P 0
(saturation pressure) transducer on the P 0 cell. Metal-
to-metal seals for critical fittings in the measurement
zones ensure the best possible vacuum performance.
The XR model’s 0.1 torr transducer extends physisorp-
tion measurement capability into the 10
-8 P/Po range
( N
2 / 77K). ‡ EPDM and Viton units only.
The Autosorb iQ has been designed to be the most flexible, versatile, and customizable gas sorption
analyzer on the market. You can purchase the requirements for your laboratory’s needs today, but have the
confidence that the instrument has the ability to expand to meet your laboratory’s future analysis needs,
without having to purchase an entirely new instrument.

Highly Precise Sample Preparation
Quality data come from properly prepared samples.
Four built-in degassing stations (with optionally inde -
pendent turbo pump capabilities) offer the user flexible
programming of automatic ramp, hold and test
protocols, including a pressure rise limit method to
minimize elutriation and steaming damage to sus-
ceptible samples. Chemisorption mode offers
c ompletely hands-free operation from in-situ
preparation including gas switching, furnace control
(heating and cooling), flow rate control (optionally
using a mass flow controller) to isotherm acquisition
without operator intervention.
Advanced Flow Methods
While the Autosorb iQ is a state-of-the-art manometric
(also called vacuum volumetric) gas sorption analyzer,
the chemisorption models are also available with
optional flow-based methods of analysis, such as
temperature programmed desorption (TPD), oxidation
(TPO), reduction and reaction (TPR), along with pulse
titration (automatic loop injection) using a built-in TCD.

models expand these capabilities further by substituting
0.1 torr transducers for ultra-low pressure (10
-8 P/P 0) physisorp-
tion measurements.
Second and third stations are available in matching MP or XR
configurations, or the simpler AG configuration.
‡High chemical compatibility version features PFE valves and
O-rings and turbo pump backed by oil pump for maximum

analytical capability is essential, and bench space is at a premium.
This is the only combined chemisorption physisorption manometric
analyzer that features four built-in degassing stations and up to
three physisorption stations for enhanced analysis throughput.
The optional TCD gives this model unparalleled capabilities
in the field. Indeed, this model is unrivaled in catalyst characteriza-
tion capability: One moment it’s a rapid surface area and pore
size analyzer, the next it is measuring active metal area and
dispersion, and even temperature programmed desorption (TPD),
oxidation (TPO), reduction and / or reaction (TPR) analyses.

Autosorb iQ-C-AG
Chemisorption and physisorption capable instrument providing
versatility and flexibility of analysis. The iQ-C-AG series includes
chemisorption hardware and software capabilities, such as a pro -
grammable high temperature (1100
oC) furnace to enable more
demanding sample treatments and analyses with more reactive
gases (hydrogen, carbon monoxide, ammonia) and, optionally,
condensible vapors. Available with a second AG (surface area/
mesopore) physisorption station.
Applications
Ideally suited for the most comprehensive
physiochemical characterization of the
surface and porous structure of discrete
solid materials. In particular, this fully
integrated analyzer is extensively used in
the fields of heterogeneous catalyst
and catalyst support R&D and for high
throughput and innovative analyses of
novel battery and solar energy materials,
chemicals and petrochemicals, gas stor-
age, purification and sequestration,
semiconductor and membrane develop-
ment, and general industrial and acade-
mic research programs for which the
most powerful yet simple instrumenta-
tion can simultaneously solve problems
and uncover new opportunities for
porous solid materials.
Applications
The chemisorption capabilities provide
more detailed and key performance in-
formation about the activity, selectivity,
stability, and regeneration of convention-
al heterogeneous catalysts and catalyst
supports. This enables users to investi-
gate ways to tailor the structure and
properties, and thus optimize the perfor -
mance and cost, of materials including
transition and precious metal catalysts
exhibiting strong, weak, dissociative and
spillover adsorption modes on specific
active surface sites, including acidic and
basic sites on metal oxides.

Measurement Capabilities & Applications
State-of-the-Art
Building on the reputation of the Autosorb name, the
iQ represents a major leap forward in gas sorption
measurement technology, providing materials science
researchers with a highly sophisticated platform to
confidently tackle any pore size, surface area or catalyst
characterization problem encountered in QC and R&D
applications alike.
For BET Surface Area: Physisorption
The Autosorb iQ can determine total BET surface
area with remarkable sensitivity. Multi-point or single
point measurements can be performed. Surface area
of 0.01 m
2/g and upwards can be determined
using nitrogen (at liquid nitrogen temperature)
or argon (at liquid argon temperature) in MP & XR
models. Using krypton at liquid nitrogen temp-
erature, surface areas down to 0.0005 m
2/g can
be measured due to the added sensitivity.
The ASiQwin software automatically displays the
BET plot and computes the BET “C” constant, y-
intercept, slope, and correlation coefficient of the
least-squares best fit. In addition, the Micropore
BET Assistant function enables the user with
the click of a button to determine the correct
linear BET range for a microporous material based
on published criteria.
Chemisorption
Some surfaces, especially catalysts, are sufficiently
reactive to form chemical bonds with certain gases.
In contrast to physisorption, chemical adsorption
(chemisorption) involves the formation of strong bonds
between adsorbate molecules and specific surface
locations known as active sites.
Chemisorption is thus used primarily to evaluate
quantitatively the number of surface active sites which
are likely to promote (catalyze) chemical reactions. Both
static adsorption isotherms and dynamic pulse titrations
yield monolayer uptake, metal area, nanocluster
(crystallite) size and active metal area of heterogeneous
catalysts. Hydrogen and carbon monoxide are the two
most commonly employed gases. Oxygen or other gases
are sometimes suitable. In an analogous manner, the
amount of acidic or basic sites is determined from the
adsorption of a basic or acidic gas, such as ammonia or
carbon dioxide, respectively. Isothermal results can be
used to map surface energetic heterogeneity via heat of
adsorption calculations.
Gas Sorption
Physisorption, or physical adsorption, is the process
by which gas and vapor atoms and molecules are
adsorbed onto the surface of a solid and which relies
on weak attractive forces, usually measured at cryogenic
temperatures. It is also the experimental means by
which one can quantify the surface area of a solid, its
pore size and pore volume distribution. Chemisorption,
or chemical adsorption, is the process of gas sorption to
specific sites through the formation of chemical bonds.
It is the experimental means by which one measures
active metal area, and related properties, of catalysts,
usually at much higher temperatures than physisorption
measurements.
Measurement Sensitivity
The sensitivity of a physisorption analysis using the
manometric technique, relying on pressure changes in
the sample cell to define the sorbed amounts, is higher
when the volume around the sample, the so called free-
space or void volume, is as small as is practicably possible,
most importantly the cold free space/void volume, since
volume for volume it contains more (unadsorbed) gas
molecules than the equivalent warm space. That is
ensured by accurately controlling the level of cryogenic
coolant around the sample cell so as to immerse as little
as is necessary for analysis.
The highest quality chemisorption measurements are
no less demanding, and are equivalently achieved by
intelligent hardware integration.

The transparent blue door encloses the

and improved temperature control.
As the coolant evaporates, the level sensor
signals the Dewar drive to compensate for
the change in level, thereby maintaining a
constant and
small cold zone.

Measurements at lower absolute pressures can also be
very effective, and this is why krypton (whose saturation
pressure at liquid nitrogen temperature is approximately
1/ 30 0
th that of nitrogen at the same temperature) is
often employed when measuring extremely low surface
areas (less than one square meter total for example).
The amount of unadsorbed gas is also a function of the
temperature of the free space: the higher it is the fewer
molecules it contains for a given pressure, and the lower
it is the more molecules are present at the same pressure.
In any manometric instrument part of the free space is
“warm” (not in coolant), and part is “cold” (submerged in
coolant). Therefore it is advantageous to minimize the
volume of free space that is cold, since every cm
3 at liquid
nitrogen temperature (77.4K) contains almost four times
as many unadsorbed molecules as every cm
3 does around
room temperature (e.g. 298K). It is true that for any cell ge -
ometry more of it should be warm and less should be cold
for maximum sensitivity. The sensitivity of a manometric sorption analyzer depends on the internal volume of the measurement zone (free
space) and how many adsorbate molecules remain unadsorbed. The goal always therefore is to minimize the amount of
unadsorbed gas occupying the free space. For example, filler rods that occupy the stem portion of the sample cell are
commonly employed. Additionally the bulbous portion of the sample cell can be selected to minimize the free space,
consistent with the bulk volume of the sample and its adsorption capacity.

Flow Chemisorption For Advanced Catalyst Characterization
(Autosorb iQ-C with TCD)
Many heterogeneous catalysts are used as the zero-valent metal, but start life as the oxide.
An important factor in catalyst
design and use is the ease of
reduction of the metal oxide and
TPR is a direct measure of that.
A reducing gas mixture, say 2%-5%
H
2 in N 2, flowing over the oxide
will cause reduction at some point as the temperature
is raised using a linear heating ramp. The signal caused
by consumption of hydrogen represents the rate of
reaction and goes through a maximum at a temperature
that is characteristic of both the oxide and the heating rate.
Repeating the same analysis on a fresh sample at
a different heating rate is the means by which activation
energy for the process can be evaluated. Low loadings
of metal oxides, especially surface oxides, generate
little water and a successful analysis can be done with-
out trapping it. Larger amounts of moisture generated
by the reduction of bulk oxides can be trapped prior
to reaching the detector to leave a clean signal based
solely on the change in hydrogen concentration.
Industrial Catalysts (eg., Hydrocracking, Hydrodesulfurization,
Hydrodenitrogenation and Fischer-Tropsch)
Carbons and carbides are amenable
to evaluation by careful oxidation
while being heated. A stream of
diluted oxygen (e.g. 2-10% O
2
in He) directed over the sample
during a linear heating ramp
generates a signal due to the
loss of O
2 from the gas stream. The
products of oxidation, CO and CO
2 ,
need not be trapped. The specially chosen filaments used
in the Autosorb iQ TCD detector are resistant to oxidation
and operate normally in the suggested gas mixtures.
Different forms of carbon such as amorphous, nanotube,
filament and graphitic, oxidize at different temperatures
due to varying availability of reactive carbon-carbon
bonds. In this way, fullerenes, soots, cokes on catalysts, etc.,
can be quickly characterized and differentiated. Oxidation
catalysts, e.g. those incorporating chromium, cobalt,
copper and manganese, and redox supports like ceria and
titania can also be characterized by TPO.
Carbons, Fuel Cells, Electrodes, etc.
S
pecies previously adsorbed can
be desorbed into a stream of
pure carrier gas to generate a characteristic fingerprint. One
very common application is
ammonia TPD, by which one
can evaluate relative acid site
strength of, for example, zeolites.
Basic sites can similarly be evaluated
b
y TPD of carbon dioxide.
Some materials may be characterized by decomposition,
or dissociation, of the bulk solid, not merely by
desorption from the surface. Such examples include
carbonates resulting from CO
2 removal studies, hydrides
used as potential hydrogen storage materials, etc.
Zeolites (eg., FCC, Isomerization)
This technique is used to
determine a wide variety of reactive material properties,
such as strong chemisorption uptake, active metal area,
metal dispersion, and average
nanocluster (crystallite) size.
After suitable in-situ preparation, which may be
combined with TPR/TPO, the sample is automatically
titrated* with small, known volumes (pulses) of reactive
gas. The detector senses the excess gas which does not
react with the sample. The total volume of gas which
does react with the sample is automatically determined
by simple back calculation using TPRWin software.

Hydrogenation, Automotive Exhaust, etc.)

The Windows®-based comprehensive control, acquisi-
tion, calculation and reporting software communi-
cates with the analyzer via Ethernet, directly or
via a LAN.
A typical physisorption analysis starts with degass-
ing of the sample. The desired protocol of heating
rates, hold times and automatic readiness testing are
loaded, and then the iQ takes over. After completing
the timed protocol, or sooner if the residual pressure
rise passes the user-defined test limit, the iQ shuts
down the degasser, backfilling the sample cell or
leaving it under vacuum if preferred.
Analysis parameters can be recalled from a saved
set, or freshly created, and can import the degassing
details. You always have a choice of analyzing using
the classical helium or, alternatively, He-free void
volume methods.
Request data at targeted relative pressure points,
automatically supplemented during the run by
additional “maximum delta volume sorbed” points
(in regions of the isotherm that show steep up-take
or desorption) or let them be acquired according to
a fixed volume dosing algorithm called Vector Dose.
When sorption takes place in large amounts and
quickly, the popular Maxidose feature minimizes
total analysis time. Hysteresis in physisorption
isotherms can be “scanned” - that is, multiple ad/
desorption cycles over desired P/P 0 ranges can be
programmed.
Comprehensive physisorption calculations include
specific surface area (single and multi-point BET,
Langmuir, STSA, t-plot, alpha-s, DR), total pore
volume and pore size distribution (BJH, DH, DA,
MP, HK, SF, Monte-Carlo, NLDFT, QSDFT) with their
corresponding surface area values, Kr pore size for
thin films, heats of adsorption, plus NK and FHH
fractals.
The DFT library is the most inclusive available
commercially, providing no less than twenty three
mathematical models describing different pore
shapes, chemical characteristics of the surfaces, and
specific adsorbate and temperature pairs.
Choose chemisorption parameters that include in-
situ pretreatment, and a second (reversible) isotherm
measurement, and combine multiple pretreatments
and isotherm analysis conditions (different gases,
different temperatures) into an extensive batch
mode.
Chemisorption results include metal area, dis-
persion, nanocluster (crystallite) size, and monolayer
capacity by a number of methods: extrapolation,
Langmuir, Freundlich and Temkin. Heats of chemisorp-
tion are also available using manometric (static
isotherm) data. Flow methods of analysis (with
the TCD option) expand the range of measurements
to include activation energy, quantitative TPD, TPO
and TPR, with the ability to deconvolute over-
lapping TPX peaks, and/or to identify effluent gases
using an optional built-in mass spectrometer.
