1.Application standards and specifications
Online gas calorific valueThe chromatographic analyzer is onlinegas chromatographOnline analysis of impurities in gas can be carried out to monitor changes in component content, providing important reference data for safe operation.
Gas chromatograph uses gas (hydrogen) as the mobile phase (carrier gas). When the sample is carried into the chromatographic column by the carrier gas through the injection system, the components in the sample are separated in the column due to differences in their distribution or adsorption coefficients on the chromatographic column. The separated components are sequentially detected by the detector. The online chromatograph has the characteristics of unmanned operation, high sensitivity, and good stability. The detection signal can be read and displayed directly or transmitted remotely, and all technical indicators can fully meet the relevant provisions of national standards.
