The GC6010 non methane total hydrocarbon online analyzer uses the GC-FID method (direct measurement method) to detect methane and non methane total hydrocarbons through low-temperature enrichment and high-temperature tracing, connected to a hydrogen flame ionization detector (FID). This instrument has a low detection limit, good repeatability, and technical parameters that fully meet the requirements of the "Technical Regulations for Continuous Automatic Monitoring of Non Methane Total Hydrocarbons in Environmental Air (Trial)" issued by the National Monitoring Center in January 2021.
