Product Description

The instrument adopts special column combination, central cutting and back blowing technology and FID technology to detect methane and non methane total hydrocarbon. After the sample is collected in the quantitative ring, the sample injection valve is switched, and driven by the carrier gas, the sample enters into the chromatographic column for separation. One way of total hydrocarbon is obtained by entering the FID detector, and the other channel of oxygen and methane are separated from the PQ column and then into the 5A column. After switching the valve position, the hydrocarbons are blown back, and the methane is detected by the FID detector.

Features
  • The patent technology of center cutting and back blowing is adopted, which meets the standard HJ / t38-1999, and directly measures methane and non methane total hydrocarbon;
  • Special chromatographic column combination was used, and the sample was kept at 180 ℃. The peak appeared within 30s, no residue and high sensitivity;
  • The instrument has power on self-test function, gas cut-off protection function, short-term automatic restart function and alarm function to ensure the safety and stability of the system;
  • FID detector has automatic ignition function and wide range output, linear range of 10-7;
  • Automatic electronic flow control (EPC) technology is used to control carrier gas, air and hydrogen, with high precision (0.01 psi), good repeatability and reproducibility;
  • The core parts are of international famous brands, with high reliability and long service life.


Scope Of Application

Environmental air on-line monitoring or scientific research, petrochemical, spraying, printing and other emissions or factory boundary on-line monitoring.
