Abstract

The invention belongs to the technical field of extraction and separation and particularly relates to a solid-phase extracting and drying device. The solid-phase extracting and drying device comprises a gas chamber cover plate, a gas chamber supporting box, a nitrogen gas inlet, a vacuum pump connector, a heater, solid-phase extraction column connectors, a thermometer, a temperature sensor, a fine-pore ceramic plate and a large-pore ceramic plate, wherein the gas chamber supporting box is in sealed match with the gas chamber cover plate; the nitrogen gas inlet is formed in one side of the gas chamber supporting box and the vacuum pump connector is arranged on the other side of the gas chamber supporting box; the gas chamber cover plate is vertically provided with the heater and the solid-phase extraction column connectors in a penetrating manner; the thermometer is fixed above the gas chamber cover plate and is connected with the temperature sensor in the gas chamber supporting box; and the fine-pore ceramic plate and the large-pore ceramic plate are transversely arranged in the gas chamber supporting box from top to bottom to form two supporting plates. Compared with the prior art, stable gas flow can be provided and the volatilization temperature of a solvent is accurate; the extraction efficiency and the gathering efficiency are high; and the solid-phase extraction and drying device has a certain practical value, the cost is reduced and the space of a laboratory is saved.

Description

technical field [0001] The invention belongs to the technical field of extraction and separation, and in particular relates to a solid-phase extraction extraction and drying device. Background technique [0002] Solid-phase extraction is a sample pretreatment technology developed in recent years. It is developed from the combination of liquid-solid extraction and liquid column chromatography. It is mainly used for the separation, purification and concentration of samples. Compared with the traditional liquid-liquid extraction method, it can Improve the recovery rate of analytes, more effectively separate analytes from interfering components, reduce the sample pretreatment process, simple operation, save time and effort. Widely used in medicine, food, environment, commodity inspection, chemical industry and other fields. With the in-depth research on the safety analysis of food, medicine and cosmetics, solid-phase extraction devices for extracting target analytes and nitroge...
