Natural chromatographic analysis

Separation for many valves and columns, TCD system analysis H₂, O₂, CH₄, CO, C₂H₆, CO₂, H₂S, C₂H₄, C₃H₈, C₃H₆, C₄, C₅, C6+ and ect.

Analytical process

The analytical system consists of a ten connection valve, two 6-way valve, four Chromatographic column and one thermal conductivity detector.

The flow diagram lies in original state, when put the sample into No. 9 mouth of valve V1 into quantitative tube 1, after sweeping clean, switch V1 from OFF to ON, carrier gas 1 takes sample into analytical column DC200, before components flowing out, switch valve 1 from OFF to ON, C₆+ was flow back to TCD, examined.

Components O₂, N₂, CH₄, CO, CO₂ and C₂ flow out from DC200 and flow into chromatographic column PQ, and when components H₂S, C₃ and above have not flowed out, switch the valve V2 from OFF to ON. Then H₂S, C₃ and above will be brought into detector TCD by gas carrier 2 and be detected, switch the valve V2 from ON to OFF. Before CO₂ and C₂ flowing out, O₂, N₂, CH₄, CO flow into chromatographic column 13X, switch the valve V3 from OFF to ON. Components CO₂ and C₂ will be detected by TCD in sequence. Switch the valve V3 from ON to OFF, components O₂, N₂, CH₄ and CO will be detected. Analysis process finish.
