Paper Abstract
A field deployable Compound Specific Isotope Analyzer (CSIA) coupled with capillary
chromatogrpahy based on Quantum Cascade (QC) lasers and Hollow Waveguide (HWG) with precision
and chemical resolution matching mature Mass Spectroscopy has been achieved in our laboratory. The
system could realize 0.3 per mil accuracy for 12C/13C for a Gas Chromatography (GC) peak lasting as
short as 5 seconds with carbon molar concentration in the GC peak less than 0.5%. Spectroscopic
advantages of HWG when working with QC lasers, i.e. single mode transmission, noiseless measurement
and small sample volume, are compared with traditional free space and multipass spectroscopy methods.
