Shimadzu GDX-104 packed column analysis of non methane total hydrocarbons in fixed pollution source exhaust gas
Detailed information on non methane total hydrocarbons in fixed pollution source exhaust gas analyzed by Shimadzu GDX-104 packed column:
Name: GDX-104 filled column
Specification: 3m * 1/8, 80-100 mesh
Number:
*High temperature: 250 ° C
Application: Determination of methane, total hydrocarbons, and non methane total hydrocarbons in exhaust gas from fixed pollution sources by gas chromatography
Applicable to Shimadzu GC-14C, GC-2010, GC-2014, GC-2018, GC-2030
In order to improve the detection level of volatile organic compounds (VOCs), environmental inspectors need to strictly determine non methane total hydrocarbons (NMHC) in fixed pollution source exhaust gas according to the HJ38-2017 standard.
Haohan chromatography uses GDX-104 methane column, summarizes the key points that need to be paid attention to in monitoring and detection technology work, analyzes each step, and provides relevant technical references for technical personnel engaged in environmental pollution monitoring and prevention.
