Non methane hydrocarbons (NMHC), as the main component of volatile organic compounds (VOCs) in the atmosphere, are important indicators for environmental pollution monitoring. With the advancement of instrumentation technology, non methane total hydrocarbon analyzers used for NMHC concentration detection are also developing towards greater precision and portability. Gas chromatography, as a commonly used method for non methane total hydrocarbon analyzers, requires measurement to be completed under specific temperature and gas flow conditions.
The 13X molecular sieve methane column developed by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has been applied to the determination of methane in fixed pollution source exhaust gas on Shimadzu GC2010. The column efficiency is high, the separation is good, and the interference of oxygen on methane is overcome. The results are satisfactory.
