Diffusion separator

Abstract

A diffusion separator comprises a thermotank, a liquid storage bottle, a sealed top cover, an outlet valve of the liquid storage bottle, a diffusion tube, an end sampling port valve and supports, wherein the thermotank is an enclosed container, the liquid storage bottle is fixed at one end of the bottom of the thermotank, the diffusion tube is connected with the liquid storage bottle to form a diffusion channel, and the diffusion tube is provided with the outlet valve and the end sampling port valve respectively at the outlet of the liquid storage bottle and the end sampling port. The diffusion separator can be used for full analysis and detection for biomass and mixture thereof. The invention is advantageous in that the diffusion separator is simple in structure, convenient to operate and strong in applicability; can summarize complex components into batches for analysis and well analyze main components; prevents interference of superposed chromatographic peaks coupled with a high performance liquid chromatography device; can protect an evaporative light scattering device, is used for identifying unknown compounds with known concentrations, and provides technical supports for complete analysis of the biomass and complex mixtures in other fields.

Description

technical field [0001] The invention relates to the field of chromatographic analysis, in particular to a diffusion separator. Background technique [0002] The detection of many organic and inorganic substances is involved in the full analysis of biomass raw materials such as leaves and fertilizers. The traditional method generally uses multiple extractions with different solvents for liquid chromatography analysis. A large number of low-concentration new substances and metal ions are produced, which will interfere with the detection of the components to be measured and cause serious damage to the evaporative light scattering detector. In order to solve these problems, this instrument is specially invented, which solves these problems well. Contents of the invention [0003] The object of the present invention is to provide a kind of diffusion separator for above-mentioned existing problem, and this diffusion separator is simple in structure, easy to operate, and applicab...
