Quick batch-sampling and separating device

Abstract

The invention discloses a quick batch-sampling and separating device, which comprises a sampling valve, test tubes, a test-tube stand, a sampling turntable, a turntable bracket, a positioning sensor, a driving mechanism, a vacuum pump, a vacuum suction head, a control device, a platform bracket and the like, wherein the sampling turntable is arranged on the turntable bracket, and is driven by the driving mechanism to rotate around the turntable bracket; the test-tube stand is arranged on the sampling turntable and rotates together with the sampling turntable; under the driving of the driving mechanism, the test-tube stand drives the test tubes to quickly move, so that samples are quickly separately arranged in the test tubes, and the requirement of quick batch-sampling is met. Meanwhile, the test tubes arranged in the test-tube stand consist of upper and lower layers of sampling test tubes and separating test tubes; and separating diaphragms are arranged in the sampling test tubes and extract and separate sampled substances entering the sampling test tubes under the vacuum condition. The device is particularly suitable for instable metabolic flow analysis requiring quick sampling, and quick batch-sampling analysis in the non-steady-state reaction process.

Description

technical field [0001] The invention belongs to a rapid sampling device and a sampling separation device for process tracking and measurement, and mainly studies unsteady metabolic flow analysis such as cell metabolism, metabolic engineering, and metabolomics, or the rapidity of material component changes in unsteady reaction processes. Measurement analysis. Background technique [0002] The cell metabolic network is composed of at least thousands of enzymes, membrane transmission systems, and signal transmission systems, which are precisely regulated and coordinated with each other. The synthesis of harmful metabolites is interrupted, and the main difficulty in design and operation is the rigidity of the cell metabolic network and the response of the cell. These microscopic reaction processes are often multi-path and non-linear, and it is difficult to truly respond only through the derivation of the results. The distribution of metabolic flow, the speed-limiting steps of k...

Problems solved by technology

At present, there is no development report of equipment in this area in China, and there are also problems of single function and simple structure in foreign rapid sampling devices. There is a lot of room for improvement in terms of operability and convenience

And for the integrated device that carries out the separation process while sampling, there is still no report at present both at home and abroad
