Laser Gas Analyzer Introduction

Laser gas analyzer is for gas measurement, developed based on tunable diode laser absorption spectroscopy. One-side mounting installation is much easier than cross-stack. By using a tunable semiconductor laser,  laser gas analyzer scans the specific absorption lines of the measured gas(no background gas) to get the second harmonic of the gas. Through processing and analyzing the second harmonic and the broadening information of the gas, the concentration of the gas is obtained.

Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.

Laser Gas Analyzer Feature

  • Non-contact optical measurement, low drift and with long service life.

  • One-side installation, no complex adjustment  of optical path required.

  • Reference gas cell adopted; online calibration; no disassemble needed

  • 'SIngle line spectrum' technology, free from interference of background gas

  • In-situ measurement, no sample conditioning required and avoiding the problems that sample is absorbed during conditioning process, blocking, unit damage and etc.

  • Low maintenance cost
