Introduction:
Gel chromatography (GPC) is the most convenient sample purification technique for separating compounds with different molecular sizes. When analyzing small molecules of organic foods, animal tissues, soils, and traditional Chinese medicines, the extracts of general samples contain a large amount of macromolecular substances, such as fats and pigments, which greatly interfere with the detection results. The GPC purification sample can remove macromolecular interference substances such as fat, protein and pigment to ensure the stability of the analysis results. The obtained small molecule component contains the target substance and impurities, and the solid phase extraction method is the main sample processing method for removing the impurity. For samples with complex matrices such as food and traditional Chinese medicine, the gel purification-solid phase extraction method has great advantages. Features:
1. The autosampler has stable performance and can be operated unmanned for a long time;
2, using stainless steel purification column, good repeatability;
3, using a full-wavelength detector, the wavelength selection is more flexible;
4, the use of imported high-pressure automatic injection valve, superior performance;
5, the use of double plunger chromatography pump, wide flow range, flow stability;
6, can use the xenon lamp - tungsten lamp combination light source, the detection range is wider;
7, can use a variety of fraction collection devices, such as: test tube (standard), nitrogen blowing bottle (optional), rotary steam bottle (optional), collection bottle (optional), etc., to reduce sample transfer loss;
8. With solvent recovery three-way valve, it can recover cleaning solvent and reduce cost;
9, using a syringe pump to draw samples, with a high degree of repeatability;
10. Solid phase extraction combined with GPC technology, with less sample loss and high efficiency;
11. Using a positive pressure type solid phase extraction device, the flow rate is controlled accurately;
12. The solid phase extraction process is fully automatic and can be operated unmanned;
13, full Chinese interface, can control all components, easy to use;
