Description:

ATQ3000 is self-designed trace gas analyzer base on the gas molecule absorbance in the range of NIR/Mid-IR. The measured relationship base on Beer-Lambert Law, say infrared light attenuation in direct proportion to gas concentration and optical length. The infrared light in specific range decided by the detected gas, go through collimating, commissioning through high speed chopper, shoot through the gas cell with the customized multi-harmonic ring-down cavity, the incident laser reflected to and pro the measured cell, and final emitted through emission port, reach to optical-electric test device and circuit board, light intensity emitted divided by incident intensity can calculate the infrared light attenuation, considering optical length is given, gas concentration can be further calculated.
