Solid-Phase Extraction (SPE) is a sample pretreatment technology, is developed by combining liquid-Solid Extraction and column liquid chromatography, and is mainly used for separation, purification and concentration of samples. Compared with the traditional liquid-liquid extraction method, the solid-phase extraction method can improve the recovery rate of the target object, more effectively separate the target object from interfering components, reduce the steps of sample pretreatment, and has simple operation, time saving and labor saving, so the method is widely applied to the fields of medicine, food, environment, commercial inspection, chemical industry and the like.
In the solid phase extraction process, the sample loading rate of a sample directly influences the recovery rate of a target object. In the operation process, the sample is inevitably attached to the inner wall of the sample tube, so that the inner wall of the sample tube is required to be cleaned, and then a cleaning reagent containing the sample passes through the column, so that the sample loading rate of the sample is improved, and the purpose of completely loading the sample is even achieved.
The inner wall of the sample tube is mainly cleaned in two ways in the prior art: the first is manual cleaning; the second is that the solid phase extraction device adds a specific reagent with the same volume as the sample into the sample tube to clean the inner wall of the sample tube by soaking. However, in any of the above cleaning methods, there is a problem that the cleaning time is long and the cleaning efficiency is low.
