I. Introduction
SS****-NH3 Extractive Laser Analysis System adopts TDLAS Tunable diode laser absorption spectroscope to measure HF concentration. It adopts special heated sampling probe which is able to work in high-temperature and high dust conditions, and hot & wet sampling system with little gas loss caused by gas condensing. Compare in-situ type gas analyzer, the extractive system has the advantages of no requirement of installation conditions, easy maintenance, little pollution to mirror, suitable for dirty sampling point with high dust.
 
II. Applications field
It is used to monitor NH3 after SNR or SCNR process in the waste incineration plant, power plant and so on.
