Introduction SPE (Solid Phase Extraction, the SPE for short) is a kind of sample pretreatment technology developed in recent years, it was based on the liquid-solid Extraction and HPLC separation mechanism was established on the basis of the combination of separation and purification methods, it is: (1) set of sample enrichment and purification at a suit, is the best way to improve the detection sensitivity. (2)Diction is quicker than the liquid-liquid extraction, saving solvent; (3) can be automated batch processing (4) with good reproducibility, etc. It Is mainly used in the separation, purification and concentration of a sample, compared with the classical liquid-liquid extraction, solid phase extraction recovery rate is high (usually above 90%), and low sample consumption, have certain selectivity, no emulsification phenomenon, etc. Method can be widely used in medicine, food, environment, commodity inspection, chemical and other fields.
There are two kinds of solid phase separation implementation sample purification way. One is reserved impurities, components under test are not reserved and natural outflow or was cleared; More common is a way to make the first completely retained in post articles to be tested, make the samples with solvent or detergent to wash out the interference impurity, and tested in small volume of solvent elution. Solid phase extraction is a physical including liquid phase and solid phase extraction process, it is the use of solid phase filler selective adsorption and selective solution to wash the components of the sample implementation of the separation, purification and concentration of the sample.
Usually solid-phase extraction plant when use the liquid samples from solid phase extraction small column top add liquid samples by solid phase extraction column bottom out. Normally, when liquid samples by post, need to exert force, through the sample liquid column bed, column bottom effluent collected another container. Our company developed the XT - SPE - type I multi-channel positive pressure type solid phase extraction apparatus using small column top pressure, can handle 1-24 samples at the same time. Through every pore of fine-tuning knob, can adjust flow velocity of each hole a truly free, to ensure that each of the extraction column flow evenly; Instrument adopts innovative serial interface, which can realize double column series extraction. Features: 1 Can handle 1-24 as a sample, can offer the same pressure of each extraction column. 2 Unique fine tuning knob, make each extraction column velocity can be independent and free adjustment, mutual interference. 3 Apply 1 ml and 3 ml and 6 ml, 10 ml and 15 ml of different specifications or capacity extraction column. Using different capacity small column, simply replace the positioning plate. 4 It Is solved by using the four innovative series extraction interface, need a lot of adsorbent or several adsorbent used at the same time, the problem of insufficient capacity of extraction column. 5 Pneumatic lifting platform, elevator control samples, at the same time provide a good air tightness. 6 Use compressed air or nitrogen, is equipped with a filter of 10 microns. 7 All pneumatic control, without external power supply. Technical parameters: 1 Sample number: handle 1-24 samples at the same time, with small column serial interface;
2 Extraction column capacity: 1 ml and 3 ml and 6 ml, 10 ml and 15 ml specification
3 Compression connection: rack pneumatic elevation, automatic sealing connection with extraction column
4: Leaching rate by air pressure control, the independent channels adjusting velocity range in 0.1-10 mL/min (according to the nature of column packing and decide)
5 Maximum working pressure: 0.5 MPa
6 Gas supply: nitrogen or compressed air (the user can use air compressor gas supply)
7 Filters: 10 microns air filter
8 Other: instrument size, 440 x 300 x 530 mm; 9 Weight of 25 Kg
