Tunable Diode Laser Absorption Spectroscopy (TDLAS)

TDLAS exploits the rotational vibrational absorption features of gases for laser-based trace gas detection. 


Key Features of TDLAS

TDLAS is a very strong tool for highly selective and sensitive measurements. It enables:

  • sensitive detection of ppm to ppb (or even ppt!) level concentrations
  • in situ measurements
  • contactless techniques
  • operation at or above room temperature
  • measurement of sticky gases
  • portable gas detectors
