Tunable diode laser (TDL) gas analyzer utilizes diode laser absorption spectroscopy (DLAS) technique. Compared to other techniques such as NDIR, gas chromatography, the result of DLAS will not be disturbed by H2O. What’s more, it features low cross sensitivities, higher resolution and higher accuracy. Thus, it has been widely acclaimed in the field of industrial process analysis, environmental pollution detection, etc.
