Product Overview
APK2350 thermal desorption instrument + APK2360 adsorption tube automatic sampler is used as pretreatment system combined with gas chromatography or gas chromatography / mass spectrometry system to realize the determination of volatile organic compounds in ambient air and waste gas from fixed pollution sources.
Application:
APK2300 series Thermal Desorption system includes two-stage thermal desorption, focused cold trap rapid heating, uniform heating inert gas path and other parts. It can be used for the determination of all 35 target compounds of VOCs in ambient air of HJ644, and the requirements of HJ734 standard for the determination of 24 target compounds in organic waste gas emitted from fixed pollution sources by adsorption tube analysis. The unique combination of adsorption tube, inert gas path and two-stage cold trap enrichment and concentration specially designed for such applications enhances the analytical ability of target compounds required by the standard.
