VSTAR

Easy Setup: M Building M P F 2 The Vstar is the star of the line of vapor sorption instruments offered by Quantachrome. The Vstar vapor sorption analyzer goes beyond water sorption to provide vapor sorption analysis using a wide variety of organic vapors at a wide range of temperatures. Meticulous control of the manifold temperature from the vapor source to the sample eliminates the possibility of local condensation of the adsorptive and ensures the most accurate analysis possible.

The screening and charac - terization of these materials is critical for iden - tifying and developing these materials for their target applications. The hydrophobicity of the material as well as its aA0pVnity to other vapors can be quickly and accurately determined using the Vstar vapor sorption analyzer. Unlike gravimetric systems, which are limited by the di@e?s`usion of the adsorptive through the carrier, the Vstar achieves equilibrium in a fraction of the time, providing results in hours instead of days or weeks. This coupled with the ability to perform four simultaneous analyses provides the material scientist with an unparalleled throughput. Food Development Optimizing the recipe of processed foods can mean the di@e?s`erence between a successful product that tastes good and has a long shelf life, and an unsuccessful product that exhibits o@e?s`-Pcavors and spoils quickly. Measurement of vapor sorption of th0(BAxnished products and the raw ingredients can provide valuable insight in the e@e?s`ective - ness of various formulations. Pharmaceuticals The evaluation of pharmaceutical active ingre- dients and excipients under various relative humidities is routinely measured using gravi- metric systems to simulate the actual condi- tions of storage and use. The measurements can be very time consuming due to the nature of gravimetric methods. Using a vacuum-volumetric system like the Vstar can provide the same information in a fraction of the time. Building Materials Building material development has gone well beyond simple trial and error with di@e?s`erent clay or cement formulations. Modern building materials, whether masonry or composites, are developed and optimized for speci!gW?c applica- tions. The Vstar can provide the information needed to evaluate various formulations for resistance to water and tolerance of solvents and other organic materials. the investigation of water vapor sorption on materials provides valuable information for material science, pharmaceutical, and food processing applications. the Vstar provides a fast, accurate, and reliable means of obtaining water sorption isotherms on a wide variety of materials, but it doesn"tat stop there. the Vstar also can measure adsorption isotherms of a variety of organic vapors, providing insight into the materialsu?esistance to organic vapors, viability as an adsorbent for these vapors in storage or sequestration applications, and information on the chemical properties of these materials.

In normal operation the status of all valves, sensors, pumps, etc. can be viewed at a glance on the controlling PC. For diagnostic purposes a password protected manual mode allows control of all valves, pumps, and heaters with the click of a mouse button. Intuitive dialogs allow programming Pcexible degas protocols and de!gW?ning all acquisition parameters, from point selection to analysis temperature. Prede!gW?ned protocols can be saved and used on a series of samples to ensure uniform analysis. Acquired data can be displayed and printed or copied into reports and other documents. Basic data processing routines such as BET surface area and Dubinin- Radushkevich are built into the basic software. Data can be exported to spreadsheets or VersaWin Quantachrome"tas powerful physisorption data processing package for additional display and processing options. 5 Specifications Performance2 Station4 Station Analysis Stations 2 4 Analysis Gas input 11 Analysis liquid input 11 Pressure transducers 1 3 5 Maximum number of optional (low pressure@??P transducers 2 2 4 Transducer accuracy 3 <0.05% FS Vacuum pump Standard external oil pump or optional internal turbomolecular pump Degas type External, optional in-situ Sample Cells Glass of various sizes Analysis temperature range 4 -20!?DFC to 100!?DFC Thermostated manifold yes (40!?DFC to 110!?DFC@??P P 0 Calculated from temperature, measured on empty station, or user entered.

For these applications we o@e?s`er several options to extend the capabilities of the instrument. Temperature Control Each Vstar comes standard with a circulating bath, with all required tubing and sample jackets. this circulator is capable of controlling the sample temperature of one to four samples fro?3c20'sB 6C to 100'sB 6C with a thermal stability o&?20.01'sB 6C*. the 2-station Vstar comes with a 7 liter circulator and the 4-station model comes with a 15 liter circulator. additional circulators can be added to allow completely independent temperature control of each sample in a multi-station system. *according to manufacturer"tas specication of circulating bath without load. actual sample temperature limits will dier depending on manifold temperature.

F 0 .1Ambient to 400 Low Pressure Operation The standard Vstar has one 1000-mbar transducer for each station and one for the manifold. In most applications this is all that is needed to precisely measure the pressure changes due to adsorption. If the optional turbomolecular pump is ordered lower pressures can be achieved. When operating at these lower pressures or with high vapor pressure liquids, optional low-pressure transducers are available to measure the small changes in pressure due to adsorption or desorption. In-Situ Outgassing For quick outgassing of samples, which do not contain large amounts of volatile material, an In-Situ outgas option is available. It consists of a furnace and controller, which can be programmed to heat the sample at a user-de!gW?ned rate and hold under vacuum for a selectable period of time. Multiple ramp and hold cycles can be programmed for each sample. 7 Sample Preparation: Degassers Consistent and reliable results depend upon proper sample preparation procedures and the limitation in analysis throughput is often sample preparation, since complete degassing of samples can often require several hours. Quantachrome manufactures several models of degassers to ful!gW?ll your sample preparation needs. These degassers provide a virtually continuous supply of properly prepared samples for the Vstar . XeriPrep Degasser MasterPrep Degasser FloVac Degasser the FloVac provides cost e@e?s`ective vacuum degassing.
