iso FLOW: An agile solution for complex problems

iso FLOW is a fully automated, continuous flow preparation system for the isotopic analysis of samples which have been prepared into septum sealed vials. These samples can be derived from a diverse range of application areas such as geoscience, climate change, food adulteration, hydrology, and clinical studies.

At the heart of the iso FLOW is the UltiTrap; a dynamically heated GC separation device. UltiTrap^TM allows greater analytical possibilities including sub-ambient GC temperatures without need for cryogenics. Coupled with unparalleled capacity for up to 180 samples and complete software control through lyticOS^® software suite, iso FLOW is one of the most flexible sample preparation systems for isotope ratio mass spectrometry.

A powerful combination: Market-leading isoprime precisION stable isotope analyzer powered by UltiTrap^TM.

High sample throughput

The iso FLOW system offers the highest sample throughput on the market with capacity for up to 180 heated samples and 220 non-heated samples to be analyzed in a single sequence. For the greatest analytical flexibility, the temperature of the heated sample tray is controlled directly from lyticOS software up to a maximum temperature of 90 °C ± 0.1 °C.

Solid state cooling with UltiTrap

At the heart of iso FLOW is our proprietary GC separation device, UltiTrap. UltiTrap can be used in different ways for different purposes. In isothermal mode, it can operate at temperatures up to 200 °C for fast analysis of simple samples. In dynamic mode, it can operate at subambient temperatures using thermoelectric cooling and rapid, dynamic heating for the improved focusing and separation of sample gases, delivering better limits of quantification for small samples.

Efficient sample preparation

iso FLOW is able to automatically prepare samples using the iso FLOW’s unique multi-core, micro-volume needle design. The instrument uses a single needle to flush sample vials, deliver reagents to the sample vial, and finally extract the prepared sample and deliver it to the IRMS for isotopic analysis. The use of a single needle makes instrument setup easier, reduces maintenance, and makes the instrument more flexible for a range of different analyses.

Carbonate Sample Analysis

The analysis of carbonate materials and dissolved inorganic carbonates (DICs) requires the delivery of phosphoric acid to digest the carbonate sample, which is performed by our direct-drive acid pump making acid delivery more precise. Automatic dosing of up to 180 sample vials in a single analysis sequence saves operators considerable sample preparation and instrument contact time.

Liquid Sample Analysis

iso FLOW delivers market-leading analytical precisions for the measurement of ?¹⁸O and ?²H isotopes of water in a range of sample matrices such as ground water, marine water, ice cores, fruit juices & purées, wines & vinegars, and biological fluids. iso FLOW uses a single equilibration gas rather than two, reducing the number of gas cylinders required in the laboratory.

Gas Sample Analysis

The analysis of gas samples requires no pre-analysis treatment, so an individual sample can be analyzed in less than four minutes, giving exceptional throughput for large numbers of samples. Sample types include breath, pure and atmospheric gases. Samples are prepared into 12 ml sample vials as standard, but other sample vials can be accommodated upon request.

Automated sample preparation and handling: Control of all flow rates and valves from lyticOS software reduces instrument contact time and consumption of resources.

High sensitivity, Great flexibility, High data quality, Ease of use. Analyze the most challenging samples with the highest degree of confidence. Cover a broad range of application areas with a single instrument. Achieve the highest analytical performance with the most precise instrument available. Easy, labor-saving instrument operation and sample preparation. Simplified maintenance.
