Abstract Information :
This paper presents a tunable laser analyzer that has the capability to analyze several components in a gas sample stream. More specifically, a multi-gas system for simultaneous detection of NH3, NO and NO2, using a room temperature distributed feedback (DFB) inter-band cascade laser (ICL) array, emitting in the 3.3-micron band has been realized. It combines all the advantages of the tunable laser spectroscopy method for a fast, sensitive and selective in-line multicomponent tunable laser analyzer. Capable of continuous monitoring of multiple components in a process stream using the TDM ( time division multiplexing) laser technology, the analyzer requires no consumables (e.g., purging, carrier gas) and no in-field calibration, bringing the overall cost of ownership down.
