Description
Technical field
The utility model relates to a kind of experimental provision, particularly relates to a kind of Simple solid phase extraction device.
Background technology
Solid phase extraction techniques is a kind of Sample Pretreatment Technique Used that developed recently gets up, and is mainly used in the separation of sample, purifying and concentrates.At present, the solid-phase extracting instrument that market occurs all has similar feature, such as, collect test tube all to need to be placed in cylinder body, in the complex process such as post activation, balance, loading, drip washing, wash-out, all need the panel taking down solid-phase extraction device, repeatedly change the test tube in cylinder body, pouring liquid repeatedly, its program is numerous and diverse, lose time, and collection vessel is restricted.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and practical Simple solid phase extraction device.
For solving the problem, a kind of Simple solid phase extraction device described in the utility model, is characterized in that: this device comprises peristaltic pump and solid-phase extraction column; Described peristaltic pump is provided with peristaltic pump tube, and the entrance point of this peristaltic pump tube is placed in liquid storage container, and its port of export is connected with the upper end of described solid-phase extraction column; The lower end of described solid-phase extraction column connects sample pipe, and this goes out in sample pipe access collection container; The entrance point of described peristaltic pump tube is connected with bayonet socket tubule, and is provided with a bead with holes.
The diameter of described bead with holes is 0.5 ~ 2cm.
The utility model compared with prior art has the following advantages:
1, due to the utility model adopt that peristaltic pump activates solid-phase extraction column, balances, loading, drip washing, wash-out process, greatly reduce During manual operation compared with conventional solid extraction equipment, have simple to operate, save time, the feature such as laborsaving; The utility model controllable flow speed simultaneously.
2, owing to being provided with out sample pipe in the utility model, therefore, solving conventional solid extraction equipment can only collect and the little problem of collected volume with Special test tube, achieves the object of any selection container.
3, the utility model structure is simple, practical, can be applied to the field such as food safety detection, agricultural product residual monitoring, medical and health, environmental protection, commodity inspection, Chemical Manufacture.
