1. The separated samples of the thin layer plate can be extracted directly without subsequent treatment;
 
2. The elution and extraction are rapid, and the spot elution can be completed in a few minutes;
 
3. No manual scraper is needed, and the operation is fast, flexible, simple and convenient;
 
4. It can be combined with mass spectrometry or HPLC system online to directly transmit the extract to mass spectrometry for detection;
 
5. Samples on the thin-layer plate can be extracted offline to the collection container, which is convenient for subsequent detection;
 
6. It can be used for preparation of thin-layer plate samples;
 
7. High efficiency and less elution solvent;
 
8. It is suitable for the extraction of strip and origin samples
