Background
With the increase of domestic detection requirements, automation in the sample detection process can be rapidly developed and popularized. Autosamplers are increasingly used as a means to automate the handling of samples in sample testing. The purging and trapping method is used together with a gas chromatograph or a gas chromatograph-mass spectrometer for measuring pollutants such as volatile or semi-volatile organic compounds, organic metal compounds and the like in liquid or solid. Typically, the autosampler handling such samples has a storage area adapted to hold a plurality of samples to be analyzed and a functional area for sample preparation. The robotic arm will typically grasp one of the sample vials and transfer it from the storage area to the preparation area. Once transferred to the preparation functional area, the contents of the small bottle are subjected to related operations such as sampling, heating, mixing, cleaning of a sampling needle and the like, so that the gas chromatograph or the gas chromatograph-mass spectrometer performs analysis and measurement.
Auto-samplers typically use separate sampling modules to extract liquid and solid samples (e.g., soil). Liquid sampling typically involves extracting a known amount of liquid from a sample vial provided to an autosampler sampling module, adding a standard to the sample, and transferring the sample to an analytical device, a process that does not require heating of the liquid sample.
