Gases absorb unique wavelengths of light and create a unique fingerprint of each compound within the absorbance spectrum; the amplitude of the absorbance wavelength is proportional to the concentration of the gas present in the sample. This is referred to as Beer-Lambert Law.

The absorption due to target gases is measured and recorded. using a pattern-matching classical least squares regression analysis, the measured absorption spectrum is compared to a vast library of stored references. The result is a real-time concentration number of the gases of interest.

Cerex’s proprietary software benefits our clients in numerous ways: unlike black box solutions, users have access to all data and can pinpoint exactly what gases are in the air at which times. Cerex is proud to have provided equipment that’s data has been relied on in court cases.
