Abstract
Description
technical field
[0001] The invention relates to an electric-driven accelerated solid-phase microextraction method and a device thereof, which is a pre-enrichment separation technology for various analysis methods and belongs to the laboratory application category. Background technique
[0002] Solid-phase micro-extraction (SPME), which integrates sampling, extraction, enrichment, separation, and sample injection, has become one of the important sample pretreatment techniques. Extraction, SPE) technology can significantly shorten the sample pretreatment time, thereby improving the analysis efficiency. For example, a complete SPE process often takes 30-60 minutes, while the SPME process can be reduced to 10-30 minutes. However, when faced with a large number of sample analysis tasks, especially compared to the large-scale instrumental measurement process that can be completed within minutes or even seconds, it is still of great significance to further shorten the time of SPME...
