GA-5000nao (NH3, NO, O2) is based on a tunable semiconductor laser absorption spectroscopy (TDLAS) and ultraviolet difference absorption spectroscopy (DOAS) technology principle, including three parts: pretreatment, gas analysis module and data processing and display. After dusting by the sampling probe, sampling by heating pipe, the measured gas is analyzed by the hot gas analysis module (TDLAS +DOAS technique). The
CEMS analyzer is an effective solution to the technical problem that ammonium salt crystallization plugs flow at low temperature, and that absorption of NH3 by condensation water leads to low measurement precision and that in situ system high dust attenuation light path leads to unmeasurable.
