Overview

The portable methane/non methane total hydrocarbon analyzer is a product of Shanghai Xuansheng Scientific Instrument Co., Ltd. By using double column, single valve, and blowback techniques, the content of methane and non methane total hydrocarbons can be analyzed in one injection. The external standard calculation method is adopted, and the results are accurate and reliable. The sample is sucked into the quantitative ring by the pump, and the switching valve allows the sample to enter the chromatographic column with the carrier gas. Methane and non methane hydrocarbons are separated. When methane flows out of the chromatographic column and enters the detector for detection, the switching valve allows the carrier gas to blow back into the chromatographic column, causing the hydrocarbon compounds (non methane total hydrocarbons) in the column to form a peak and blow back to the detector for detection. This instrument can achieve online multi-point monitoring according to user needs.

Product Details

Based on the characteristics of high water vapor content, high concentration, and complex working conditions of organic waste gas, and in accordance with the HJ/T38-1999 standard, a laboratory non methane total hydrocarbon chromatographic analyzer was designed and developedportableAfter being filtered by a built-in filter, the sample is collected into a quantitative ring. The sample in the quantitative ring is then sent to a chromatographic column for separation through the action of a carrier gas. The separated components are sequentially detected by a FID detector to obtain accurate qualitative and quantitative analysis results.

portableOn the premise of meeting various performance requirements, the methane/non methane total hydrocarbon analyzer should achieve the strongest practicality according to the specific requirements of users,.

Portable methane/non methane total hydrocarbon analyzer

Instrument characteristics

The GC-9850 portable chromatograph uses a high-sensitivity FID detector.

• Independently developed electric injection valve

Full process high-temperature heat tracing pipeline transmission (optional) and high-temperature FID detection can effectively avoid sample loss.

The modular structure is compact and reasonable, with multiple expansion functions, accurate and fast analysis, and more convenient installation and maintenance.

On the basis of full reverse control function, real-time display of various data spectra.

External control events can achieve automated operation of instruments. Accurate qualitative and quantitative analysis and detection of methane/non methane total hydrocarbons, as well as benzene, toluene, and xylene substances, in conjunction with automatic injection valves and chromatographic columns;

The instrument has functions such as power on self-test, power-off protection, automatic restart, and automatic ignition, ensuring high sensitivity, stability, and repeatability of the entire instrument.

• It has functions such as sample filtration, decompression, extraction, etc

The automatic sampling system can be connected to various sample inputs, and the data processing system can be integrated with the data transmission modules of various central control systems to ensure real-time sampling, remote control, real-time transmission, and real-time results.
