The solid phase micro-extraction technology can be almost used for analyzing various volatile or semi-volatile substances in samples such as gas, liquid, biology, solid and the like. The development time is as short as 10 years, and the method has been widely applied to various aspects in the fields of environment, biology, industry, food, clinical medicine and the like. In the development process, the development of a solid-phase coating material and a coating technology, an extraction method and a coupling technology of the probe, further improvement of theory, application and the like are mainly involved.
At present, most of experiments of solid-phase microextraction are manually operated, reagent tubes are inevitably knocked over during extraction, and each extraction is basically carried out by one reagent tube, so that confusion is easy to generate, and the experiment time cannot be prolonged.
