Application: GBT 6021-1999 Determination of oxygen and argon in the gas phase above liquid butadiene for industrial use by gas chromatography
The gas sample is injected into the chromatograph through the sampling device, and is carried into the pre-separation column by the carrier gas. After the hydrocarbons are adsorbed by the pre-separation column, the pre-separation column is backflushed to vent the hydrocarbon components. The rest of the components enter the separation column for separation and are detected with a thermal conductivity detector. Since oxygen and argon are not separated on the separation column at ambient temperature, argon is used as the carrier gas, so that the argon in the sample does not respond on the thermal conductivity cell. The oxygen content in the sample was determined by comparing the obtained oxygen chromatographic peak area with the oxygen chromatographic peak area obtained from the standard sample.
