Packed column for determination of exhaust acrylonitrile from stationary pollution source
Aerated acrylonitrile determination of fixed pollution source exhaust packed column details:

Stationary phase: polymer beads
Model: GDX-502
Specification: 3m * 3mm
Granularity: 60-80 mesh
Material: stainless steel / glass / PTFE
Application: Determination of acrylonitrile in exhaust gas from fixed pollution sources


Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. used GDX-502 packed column to compare the monitoring results of acrylonitrile in ambient air by GC- gas chromatograph on site, and found that the two sets of monitoring data have some consistency The correlation is not high. The reasons for the data differences are analyzed, and the single-point calibration method is discussed, which improves the accuracy of the gas chromatograph to determine the concentration of acrylonitrile in the ambient air at the emergency scene.
