About Trace Gas

The TGA100A Trace Gas Analyser measures trace gas concentration in an air sample using tunable diode laser absorption spectroscopy (TDLAS). It is a rugged, portable instrument designed for use in the field. Common applications include gradient or eddy covariance flux measurements of methane or nitrous oxide and isotope ratio measurements of carbon dioxide or water vapor.
