The Fid analyzer, namely the Flame Ionization Detector analyzer, is a highly sensitive gas analysis instrument. It uses the ionization effect of a hydrogen flame to detect organic compounds in gases and can accurately measure the contents of various organic substances. The outer shell is made of special heat - insulating and explosion - proof materials to ensure safety and reliability during the detection process and adapt to various complex detection environments. Its advantage lies in its extremely high sensitivity, good response to most organic compounds, and a wide detection range, meeting the needs of different industries for organic gas analysis. It is widely used in fields such as petrochemicals, environmental monitoring, and food testing. In the petrochemical industry, it analyzes the organic gas components in the production process; in environmental monitoring, it detects volatile organic compounds in the atmosphere; in food testing, it analyzes the gas components in food packaging to ensure food quality.
