Gas chromatograph: equipped with nitrogen phosphorus detector (NPD)a

natural gasIntroduction to Gas Analysis Chromatography:

GC-7890 natural gasThe chromatographic analyzer solves the problems of nitrogen, carbon dioxide, and other pollutants with automatic sampling, automatic injection, automatic data acquisition, and automatic valve cutting in one injectionMethane, ethane, propane, n-butane, isobutane, n-pentane, isopentane, hydrogen sulfideWait for a complete analysis of the gas. This instrument can achievefully automatic operationBy laying pipelines, the tested gas is pumped from the vacuum pump to the gas chromatograph for detection. The detection results are automatically processed by the analysis software, and the entire process is controlled by a microcomputer,the instrumentReduced the workload of analysts and improved work efficiency;rightNatural gas and liquid quality testing providesReliable data. All analyzed data can be retained for staff to reuse.In response to this phenomenon, Shanghai Xuansheng Company has developed a portable fully automatic gas calorific value analyzer to recover losses for LNG users. It can achieve full analysis of nitrogen, methane, ethane, propane and other components in LNG, as well as high calorific value, low calorific value, density, relative density, white number, combustion potential and other parameters.

Characteristics:

◆ With the new generation of high-performance and high stability GC-7890Based on gas chromatography, it operates reliably and stably;

One injection solved the problemNitrogen, carbon dioxideMethane, ethane, propane, n-butane, isobutane, n-pentane, isopentaneComplete analysis of gas; Increase FPD detector can detect simultaneouslynatural gasChineseTrace amounts of hydrogen sulfide, etccontent

Using the application of central cutting technology, multi column parallel series technology, and multi detector parallel series technology, full component analysis is conducted on natural gas, liquefied gas, and other gases.

• This machine integrates analysis columns, detectors, and working software, which is suitable for both online pipeline detection in industrial sites and airbag sampling analysis in laboratories;
• Dual channel calorific value working software, automatically calculates the detected gas component content, high calorific value, low calorific value, density, relative density, Huabai number, combustion potential, etc;
• dual gas pathInjection valve to improve the repeatability of detection results;
• Can be equipped with mouse and printer
