La description

I. Introduction
The SS***0 process VOCs monitoring system is based on the standards of HJ/T*0, HJ/T*5, HJ/T*6 and other related standards, sampling by extraction method, configuration based on advanced gas chromatography, mass spectrometry separation technologies and hydrogen flame Ionization Detectors (FID), photoionization detectors (PID) to measure the composition of volatile organic gases such as total hydrocarbons (THC), non-methane total hydrocarbons (NMHC), aromatic hydrocarbons, esters, etc. According to the composition and detection requirements in the analysis project, it can be configured to meet the requirements of the analysis project and the frequency of analysis. At the same time, the optimization of instrument configuration can be performed to maximize the use of the instrument and ensure the continuity of sample analysis. reliability.
 
The analysis system fully considers sample gas conditions, dew point and other factors, and specifically designs the pretreatment system to prevent the crystallization of components in sample gas from condensing and changing the concentration of components.
 
The instrument uses special column combination, center cutting and back blowing technology and hydrogen flame ionization detector (FID) technology for detection. The FID Hydrogen Flame Ionization Detector is a typical mass detector that measures the mass change rate of a component in a GC gas. The response value is proportional to the mass of a component entering the detector per unit of time.
 
II. Features

  • The system piping is imported clean stainless steel pipe to reduce adsorption;
  • The system adopts full calibration to eliminate the influence of a small amount of adsorption on the measurement.
  • The analytical method is consistent with the calibration method, and it is detected by GC-FID method.
  • The whole process of high-temperature **0 °C with hot sample transmission, high temperature FID detection, to avoid high-boiling VOCs adsorption and condensation, more accurate measurement;
  • Continuously run maintenance-free design, start-up automatic cycle operation, real online analysis;
  • The whole flow path insulation design is **0°C, no water vapor condensation, to avoid corrosion degradation of parts, suitable for high temperature / high humidity / corrosive conditions;
  • Non-methane total hydrocarbons and simultaneous monitoring of benzene, toluene, xylene and other components
