Determination of non-methane total hydrocarbons from stationary pollution sources GDX-502 methane column
Determination of non-methane total hydrocarbons from stationary pollution sources GDX-502 methane column Details:
Name: Packed Column
Stationary phase: polymer beads
Specifications: 2m*1/8
Granularity: 60-80 mesh
Model: GDX-502
Application: Determination of ambient air, stationary pollution source waste gas/methane/total hydrocarbons/non-methane total hydrocarbons
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses volatile organic compound standard gas to determine the gas bag and valve body material, heating temperature before injection, sample storage time, etc. At the same time, four typical industries, such as petrochemical storage and transportation, paint production, industrial coating, packaging and printing, were selected to verify the actual samples. The results show that the blank values of FEP-inlet and PVDF-inlet air bags are the lowest; the deviations of all kinds of air bag samples heated to 80 ℃ are greater than 60 ℃, and it is recommended to control the heating temperature at 60 ℃; for samples with complex components, it is recommended that the storage time should be within 8 hours.
