According to the national standard GB/T13610-2003 "Gas Chromatography for Component Analysis of Natural Gas", Tengzhou Zhongke Spectral Analysis Instrument Co., Ltd. has developed“LNG liquefied natural gas analysis integrated machineThe specific functions are as follows:

1. Configure a highly sensitive thermal conductivity detector to measure the content of N2, CO2, CH4, C2H6, and C3H8 components in natural gas

2. One time automatic injection for full analysis, displaying all tested components on a single analysis spectrum;

3. Natural gas is introduced into the chromatography chamber through a bypass in the pipeline to achieve real-time detection of the quality of the flowing gas in the pipeline. The instrument can be remotely operated through a network cable in the control center. B. There is an automatic timed loop analysis function, and the analysis data can be automatically saved and sent to remote files;

4. A reliable self checking system enables the instrument to operate online for a long time, with only H2 as the carrier gas, making operation simple and convenient; C. The intelligent peak detection method is suitable for the long-term operation of the instrument, and due to the absence of flame detectors, it meets the requirements of on-site safety.

At present, China's gas chromatography method is used for the analysis of natural gas components, but there is no corresponding national standard for adding nitrogen to natural gas. Tengzhou Zhongkepu's portable natural gas liquid nitrogen detector designed according to market demand uses an external standard method, and the detector uses a thermal conductivity detector (TCD) for qualitative and quantitative analysis of nitrogen in natural gas
