Introduction: In the food analysis, macromolecular interferences in the sample matrix cause high noise, many peaks, and can contaminate the chromatographic inlet, ion source, and the life of the column. Gel permeation chromatography (GPC) is based on the principle of volume exclusion effect to achieve separation and purification purposes. GPC can effectively elute macromolecular impurities first, and then elute with relatively small molecular mass substances. Shanghai Kezhe Biochemical Technology Co., Ltd. has launched a four-channel gel purification system to meet high-throughput samples of food in China. Pre-processing needs. Features: 1. The instrument has four independent channels, which can process four samples at the same time; 2, four channels can be controlled independently, one machine is equivalent to four machines; 3. Independent four sets of pump systems can be controlled independently; 4. Sample purification and segmentation can be performed; 5. Four sets of automatic fraction distribution valves can realize automatic distribution of fractions; 6. It can be purified by four different sizes of GPC columns and four different mobile phases; 7. Four channels can be set to four different methods to meet various application needs; 8, can use any one or more of the channels independently; 9, single-wavelength detector, long life of light source, higher cost performance; 10. The system is suitable for plunger chromatography pump, with wide flow range and low failure rate; 11. Four-channel chromatography workstation, each channel is independently monitored; 12, prefabricated stainless steel gel column, excellent reproducibility; Technical Parameters: Flow range: 0-50ml/min; Flow stability: ±1%; Detection wavelength: 190-800 nm; Column: 25 × 400mm; Number of channels: 4 channels (expandable to 10 channels
