Portable Gas Analyzer Based on Fourier Transform Infrared Spectrometer for Patrolling and Examining Gas Exhaust

Figure 1

Schematic diagram of the portable gas analyzer based on an FT-IR spectrometer. The storage cell provides power for FT-IR spectrometer, gas pump, and micro-PC. The gas pump is used to pump the analyzed gas into gas cell. Sensors include temperature and pressure. They are used to monitor the temperature and pressure of analytes for compensating the effects of gas temperature and pressure on gas concentration. A micro-PC reads the absorption spectrum of analyte and performs the spectrum analysis.
