On-line concentration system suitable for large-flow enriching instrument

Abstract

The invention provides an on-line concentration system suitable for a large-flow enriching instrument, wherein the upper part of a solution cache container is provided with a condensation backflow module; the lower part of the solution cache container is provided with a heating and cleaning module; the upper end of the solution cache container is provided with an input tube, an output tube and a steam recovering tube; the input tube is communicated with a solution input pipeline; the output tube is communicated with a solution output pipeline; the steam recovering tube is communicated with a solvent recovering module; the solution output pipeline is provided with a solution output pump; the lower end of the solution cache container is provided with an effluent discharging pipeline which is controlled by an effluent discharging pump; the interior of the lower end of the solution cache container is provided with a liquid level detection control plate; the solvent recovering module is connected to a cleaning pump; and the condensation backflow module, the heating and cleaning module, the solvent recovering module, the solution output pump, the effluent discharging pump and the liquidlevel detection control plate are all controlled by a control system. The on-line concentration system has the advantages that the design is smart, the occupied space is small, the system can be usedtogether with the large-flow enriching instrument so as to realize the automatic operation and save the processing time, and the like.

Description

technical field [0001] The invention relates to an on-line concentration system, in particular to an on-line concentration system which can be matched with a large-flow enrichment instrument, realize automatic operation, and save processing time. Background technique [0002] In a large-flow enrichment instrument, due to the large flow, there will inevitably be more dead ends in the enrichment tube and other positions, so it is necessary to use tens of milliliters or even hundreds of milliliters of solvent during elution, which leads to the final The eluted solution to be tested also needs to be processed in the laboratory (such as concentration treatment, etc.) before it can be analyzed and tested on the machine, and online analysis cannot be realized. However, samples are often contaminated during transport to the laboratory, and the operation of the laboratory cannot ensure consistency, which will lead to time-consuming, labor-intensive and many problems. Therefore, ther...
