CAS Product Configurations
Whether alone or coupled with front-end samplers, a CAS system effectively and efficiently makes the very best use of the smallest sample sizes. The CAS can be configured to target a range of molecular species. Standard configurations measure CO2 and/or H2O, which custom configurations are available for CH4, N2O, H2, CO, and many other species.
Single Species CO2 CAS-300
Dual Species CO2/H2O- CAS 300/1500
Custom Build CAS
CAS-300 CO2
The CAS-300 CO2 is a single species carbon-dioxide, isotope measurement system with a 300-micron internal diameter hollow fiber gas cell.
Suitable for direct gas measurement of discrete samples or in continuous flow
Simple integration with Gas Chromatograph (GC) front end
Configurations available for single isotope: δ13C or multi-isotope: δ13C, δ18O, and δ17O
CAS-1500 CO2 H2O
The CAS-1500 CO2 H2O is a dual species, carbon-dioxide and water, isotope measurement system with a 1500-micron internal diameter hollow fiber gas cell.
Suitable for direct gas measurement of discrete samples or in continuous flow
Rapid gas cell fill time, ~ 1 second
Multiple isotopes: δD-H2O, δ18O-H2O, δ17O-H2O δ13C-CO2, δ18O-CO2, δ17O-CO2
Custom Build CAS
Custom build CAS analyzers can be configured for a variety of single or multi-species measurements for isotopes and/or concentrations of various gases.
Configurable for isotope measurements of Methane, Nitrous Oxide and others
Available for the concentration measurements of Methane, Hydrogen, Nitrogen Oxides, HF, and others
New gas application development is available upon request.

CAS for Coupled Technologies
The low sample volume and non-destructive measurement of the CAS analyzers enables effective coupling with other technologies.
Front-end analyzer for mass spectrometry or other complimentary instruments
Back-end analyzer for sampling techniques, such as laser ablation or gas chromatograph
Customized interface hardware is available or can be custom designed for your application.
We partner with Activated Research Company (ARC) for all Gas Chromatograph applications.
