  GDX-502 is a white porous microsphere, a polymer composed of divinylbenzene and acrylonitrile. It has good thermal stability, corrosion resistance, and radiation resistance, and belongs to the category of medium strong polarity fillers. Its apparent density is 0.33g/ml, specific surface area is 80m ²/g, and the maximum operating temperature can reach 250 ° C.
In terms of application scope, it is suitable for the analysis of C1 and C2 hydrocarbons and CO, CO2, and can completely separate ethane, ethylene, and acetylene. Specific applications include the determination of total hydrocarbons, methane, and non methane total hydrocarbons in ambient air; Determination of total hydrocarbons, methane, and non methane total hydrocarbons in exhaust gas from fixed pollution sources; Determination of dissolved gases CO2, ethylene, ethane, and acetylene in transformer oil; Determination of methane in biogas; And analysis of industrial gases such as coke oven gas and refinery gas.
Name: Methane Column
Model: GDX-502
Specification: 2m * 4mm, 60-80 mesh
Zui high temperature: 250 ° C
Application: Determination of total hydrocarbons, methane, and non methane total hydrocarbons in fixed source exhaust gas/ambient air by gas chromatography, HJ-1999,hj-2017
GDX-502 is widely used for environmental and industrial gas analysis and complies with multiple national standards:
environmental monitoring
HJ 604-2017 (Environmental Air Total Hydrocarbons/Methane/Non Methane Total Hydrocarbons)
HJ 38-2017 (Fixed Source Waste Gas Total Hydrocarbons/Methane/Non Methane Total Hydrocarbons)
HJ 1286-2023 (Technical Specification for Continuous Monitoring of Non Methane Total Hydrocarbons)
GDX-502 is an ideal choice for environmental and industrial gas analysis, and its performance is significantly affected by column length and instrument adaptation. A column length of 5m can solve the problem of O ₂/methane interference, especially suitable for high standard monitoring such as HJ 604-2017. During use, it is necessary to strictly follow the aging and deoxygenation process to extend the column life and ensure data accuracy.
