Introduction Preval SPE automatic solid-phase extraction system is a large capacity closed three-dimensional vertical solid-phase extraction system, without manual intervention can complete all the steps of solid phase extraction, solid phase extraction column, the activation, sample addition, leaching and elution experiment steps. With the method of positive hydraulic injection control liquid velocity and precision, to ensure that the liquid transmission accuracy and reproducibility. Features Solid phase extraction technology based on the theory of liquid - solid chromatography, adopt the way of selective adsorption, selective elution so that it is separated from the sample matrix and interfering compounds. The basic principle of SPE and HPLC of the same but different, SPE is mainly used in the sample separation, purification and concentration, thereby reducing the sample matrix interference, improve the detection sensitivity. Technical Parameter 4, 6, 12, multi-channel Batch processing: 88, 56, 40, 20 Positive pressure a column Fully enclosed operation Wireless touch screen control No damage on the sample function Distillate collect more functions Can upgrade online nitrogen blow heat concentration Can upgrade column in series Apply to all kinds SPE column and solid phase extraction column for diaphragm aflatoxin. Etc Large volume collection function Fully automated, directly to a column collecting liquid transferred to various models spin steaming inside the bottle, one pace reachs the designated position, do not need to transfer again Applicable to collect bottle type Flat/round bottom flask, heart and tomato shape bottles, bottle blowing nitrogen, etcThe nitrogen bottle blowing collection
