[technical field]
The utility model relates to SPE field, specifically a kind of simple and quick solid-phase extraction device.
[background technology]
SPE (Solid Phase Extraction, be called for short SPE) is a Sample Pretreatment Technique that starts to grow up mid-term from the eighties.By liquid-solid extraction and liquid chromatography technology, combine and develop.Be mainly used in the separation of sample, purify and enrichment.Main purpose is to reduce sample substrate and disturbs, and improves detection sensitivity.
Solid phase extraction techniques, based on liquid-solid phase chromatographic theory, adopts the mode of selective absorption, selective elution to carry out enrichment, separation, purification to sample, is a kind of physical extraction process that comprises liquid phase and solid phase; Also it can be regarded approx as to a kind of simple chromatographic process.
SPE is the liquid chromatography separation principle of utilizing selective absorption and selective elution.More conventional method is to make fluid sample solution by adsorbent, retains wherein measured matter, then selects suitable intensity polar solvent to wash away impurity, then uses the rapid wash-out measured matter of a small amount of solvent, thereby reaches quick isolation of purified and concentrated object.Also alternative adsorptive hindrance impurity, and allow measured matter flow out; Or adsorb impurity and measured matter simultaneously, re-use suitable solvent selectivity wash-out measured matter.
Existing solid-phase extraction device is because the waste liquid in extraction column activation, loading and lessivation will flow in waste liquid bottle rather than in receiving flask, so can not put into collection bottle stand while starting, emptying open extraction equipment upper cover collection bottle stand is put into collection extract again after drip washing, so just there is complex operation, to experimenter, bring the trouble of operation.
