| description | The invention provides an on-line chromatographic analyzer sample pretreatment system for natural gas component measurement, which comprises a sample input pipeline, a gas circulation pipeline and a quantitative measurement pipeline, and is characterized in that the sample input pipeline is connected to a three-way valve in the gas circulation pipeline, the gas circulation pipeline comprises a plurality of circulation branches, and the quantitative measurement pipeline is connected to the three-way valve in the gas circulation pipeline. And the circulation branch for component detection is communicated with the ten-way valve in the quantitative measurement pipeline. Through the pretreatment system provided by the invention, impurities can be removed from a just mined natural gas sample before component measurement, meanwhile, real-time updating and quantitative measurement of the system sample are ensured, and the accuracy of the natural gas component measurement chromatographic analyzer is improved.
