CAS Technology
The CAS concept is a versatile platform configurable for a range of applications and lasers, including but not limited to methane and carbon isotope measurements, isotope analysis of laser ablated samples, and trace gas analysis from biological samples.
CAS ANalyzer
The Analyzer
The Capillary Absorption Spectrometer (CAS) system utilizes proprietary hollow core fibers produced by Guiding Photonics. The hollow fiber has a reflective coating that guides a laser beam from source to detector. Within the hollow fiber a probe beam and analyte overlap enabling sensitive laser absorption spectroscopy with minimal sample size for trace-gas and isotope analysis.
CAS Assembly
Key Components
The hollow fiber cell can be coiled into a compact form factor. In addition, it has a relatively small internal sample volume (as low as 1 mL), which enables trace gas and isotope analysis with minimal sample requirements.

Features
CAS Advantages
Small Sample Sizes
Cabon isotope analysis with less than 1 picomole of carbon
Low-cost Analyses
Significantly lower upfront cost compared to isotope ratio mass spectrometry (IRMS) systems
Small footprint
System is the size of a large shoe box (i.e., work boot size)
Rapid analysis
Real-time isotope ratio values updated at 1 second rates, values can also be averaged for higher precision
Low Maintenance
Does not require extensive calibration or high vacuum hardware, reducing labor costs associated with maintaining competing systems
Doesn’t require a PhD
Intuitive software for data collection, real-time measurements, and post-processing analysis
