Introduction: Gel permeation chromatography (GPC) can be separated compounds of different molecular size, is the most convenient sample purification technology. For food, animal tissue, soil, small molecule organic compound Chinese medicine when analyzing the general sample extract contains a large number of large molecules, such as fat, pigment, will greatly interference detection the results by GPC purification samples, can remove the fat, protein, pigment and other large molecular substance, to ensure the stability of the analysis results. In order to meet the high throughput sample food safety demand in China before processing, our company has developed GelMaster automatic GPC gel purification system, mainly used to solve the problem of food safety, drug safety before treatment sample. Characteristic： 1 integrated design, more concise, more robust, integrated national leader; 2 automatic sampling device performance is stable, can be a long time unmanned operation; 3 the use of pressure resistant glass column for separation, easy to observe the ribbon; 4 using high-pressure plunger pump, pressure up to 6000PSI, can use high-pressure column; 5 using the full wavelength detector, the wavelength selection is more flexible; 6 can be equipped with a bottle cap puncture device, you can use a sealed sample bottle; 7 using imported high pressure automatic sampling valve, superior performance; 8 the use of double plunger pump, a wide range of flow, flow stability; 9 the combination of deuterium lamp and tungsten lamp can be used to detect a wider range; 10 can use a variety of fraction collection devices, such as: test tube, nitrogen blowing bottles, rotary steam bottles, collecting bottles, etc., to reduce the loss of sample transfer. 11 can be directly connected with solvent recovery three-way valve, Recyclable cleaning solvents, reduce the cost; 12 can be directly connected to the quantitative concentration device, so that the samples are concentrated in mild conditions; 13 using the plunger pump to draw samples, with a high degree of repeatability; 14 full Chinese interface, can control all the components, easy to use; 15 product performance than imported equipment, the price is much lower than the import equipment Main composition: 1 pairs of plunger type high pressure gas chromatography pump; 2 full wavelength ultraviolet detector; 3 special GPC column; 4 full automatic fraction collector; 5 full automatic sampling device (including injection pump); Main index: 1 Flow: 0-50ml/min; 2 maximum pressure: 6000PSI (higher pressure can be customized); 3 flow stability: + 0.5%; 4 automatic sample volume: 0~10 ml (2ml or 5ml); 5 collector: can accommodate 30X200mm test tube 45 or 15X200mm test tube 168; 6 UV detection wavelength: 190~700nm; 7 chromatographic column: 25X400mm; 8 automatic sampling quantity: 160 maximum;
