Our Technology
The CAS concept is a versatile laser spectroscopy platform configurable for a range of applications, including but not limited water and CO2 isotope measurements, analysis of GC peaks, 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 the 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
Guiding Sensors introduces a new class of analyzers leveraging the ultra small sample size of our proprietary hollow core fibers for high precision measurements in sample limited applications.
