Determination of Total Hydrocarbons and NMHC in Ambient air-Gas Chromatography, Shanghai HengPing Instrument and meter Co.,Ltd. (CAT#: STEM-AI-0412-YJL)

Determination of Total Hydrocarbons and NMHC in Ambient Air-Gas Chromatography, model STEM-AI-0412-YJL is manufactured by Shanghai HengPing Instrument and meter Co.,Ltd. Hydrocarbons that pollute ambient air generally refer to volatile hydrocarbons (C1~C8). Two methods are commonly used to represent: one is hydrocarbons including methane, called total hydrocarbons (THC), and the other is hydrocarbons other than methane, called non-methane hydrocarbons (NMHC). In general, non-methane total hydrocarbons have a direct relationship with the combustion of coal, petroleum and other fuels and the emission of vehicle exhaust.
The instrument adopts ten-port valve double quantitative loop sampling, double column parallel single detector detection, can analyze and detect total hydrocarbons and non-methane total hydrocarbons in ambient air with one sample injection, with good repeatability and high accuracy. The instrument has a built-in non-methane total hydrocarbon chromatography workstation, which has the functions of intelligent identification/automatic processing of spectral peaks, integration and exchange of multi-channel spectra, automatic deduction of methane content and oxygen peak interference, etc.

LCD screen or 5.7-inch color touch screen;
All microcomputer computer counter control system, a single computer can control less than 253 chromatographs, with 7 channels of temperature control; 8 channels of external event time programs;
The instrument has a built-in non-methane total hydrocarbon chromatography workstation, which has the functions of intelligent identification/automatic processing of spectral peaks, integration and exchange of multi-channel spectra, automatic deduction of methane content and oxygen peak interference, etc. ;
The instrument adopts RJ45 network cable interface, signal output, control and acquisition are simple and convenient, which can realize remote control of the instrument and remote data transmission processing and supervision. It can be connected to the supervisor of the unit and the superior supervisor, which is convenient for supervisors to implement supervision;
Large-capacity column oven with automatic back door, 8-step temperature programming, and control function of column oven near room temperature (5°C above room temperature);
It has the function of fault self-diagnosis, which can display the fault location and nature; it has the function of over-temperature protection, and the heating will automatically stop if the temperature of any route exceeds the set temperature.
