The company’s self-developed ultra-high-precision trace gas detector based on the principle of light absorption, with the highest accuracy of one trillionth, filling the gap of this precision level in the world.
The instrument can detect formaldehyde, glyoxal, NO, NO2, NO3, N2O5, O3, peroxynitrate, alkyl nitrate, nitrite, water vapor, particulate matter extinction, iodine oxide, iodine vapor, bromine vapor, aerosol extinction, etc. It can be widely used in atmospheric environment detection and analysis, ocean atmosphere detection and analysis, pharmaceutical analysis experiment, analysis experiment in the field of petrochemical industry; It can also be used for the calibration of the above gas detection equipment, and it is the first time to realize the calibration of atmospheric monitoring instruments without the participation of standard gases.
