Abstract

The invention relates to a microwave high pressure extraction container, which takes silicon nitride ceramic material as a tank body to realize microwave high pressure supercritical fluid synchronous coupling extraction of different organic compounds in samples inside the tank. The microwave high pressure extraction container mainly consists of a tank body, an upper cover, a connecting bolt and a sealing pad. The upper cover is provided with a high pressure fluid inlet, a high pressure fluid outlet, a pressure monitoring mouth and a safety valve connector. The tank body is connected into a whole with the upper cover by the connecting bolt, a connecting nut and the sealing pad. The high pressure fluid inlet and the high pressure fluid outlet are respectively communicated with the internal chamber of the tank body. The microwave high pressure extraction container of the invention has the function of realizing effectively extracting different organic compounds in microwave supercritical fluid synchronous coupling extraction samples, is beneficial for the high efficiency purification extraction and preparation of different organic compounds in the fields of environmental monitoring, chemicals, pharmacy, etc., and is especially suitable for the high efficiency extraction of different organic compounds in solid/ half-solid samples.

Description

technical field [0001] The invention relates to a microwave extraction container, in particular to an extraction container used for synchronous coupling extraction of different organic substances in a sample by microwave high-pressure supercritical fluid. Background technique [0002] Microwave-assisted extraction (MAE) and supercritical fluid extraction (SFE) are important components of modern chemical analysis techniques, and play an important role in sample pretreatment and detection. Microwave-assisted extraction utilizes the high penetration performance of microwaves, and has the advantages of rapidity, high efficiency, and easy operation. Supercritical fluid extraction utilizes the characteristics of high critical point, high density and low viscosity of supercritical fluid to continuously distribute and exchange dissolved samples between gas phase and liquid phase to achieve better separation. [0003] The microwave high-pressure supercritical fluid extraction system...
