Embodiment Construction

[0014] Specific embodiments of the present invention will be further described in detail below.

[0015] Such as figure 1 As shown, a multi-channel solid phase extraction glass column of the present invention includes a substrate 10 made of strengthened glass. Eight straight extraction pipes 12 parallel to each other are arranged in the middle of the substrate 10 . Both ends of the extraction pipe 12 are provided with outlets 14 connected to the outside of the substrate 10 . An extraction filler 16 is arranged in the extraction pipeline 12, and the extraction filler 16 is carbon 18 or silica gel.

[0016] Such as figure 2 and image 3 As shown, a multi-channel solid phase extraction glass column of the present invention includes two parallel substrates 10 stacked together. The opposite inner side of the substrate 10 is provided with a half-through groove 18 , and after the two substrates 10 are stacked together, the half-through groove 18 on the two substrates 10 forms a...

Abstract

The invention provides a multichannel solid-phase extraction glass column. The multichannel solid-phase extraction glass column comprises a substrate which is made from toughened glass. The multichannel solid-phase extraction glass column is characterized in that: a plurality of linear extraction pipelines which are mutually parallel are arranged at the middle of the substrate; two ends of the extraction pipelines are provided with outlets which are communicated with the outside of the substrate; and extraction filling materials are arranged in the extraction pipelines. The multichannel solid-phase extraction glass column provided by the invention has the beneficial effects that: by using the toughened glass as the substrate, the multichannel solid-phase extraction glass column has the advantages of attractiveness, corrosion resistance, stable structure, easiness for processing, transparency, excluding of plasticizing agents and the like; and in addition, with the adoption of the eight-channel extraction pipelines, a plurality of samples can be simultaneously processed, thus the operational efficiency is high.

Description

technical field [0001] The invention relates to a chemical device, especially a solid phase extraction device. Background technique [0002] In the field of food, environment and drug safety testing, sample pretreatment is a very important step. The quality of sample pretreatment not only affects the final analysis results, but also affects the service life of analytical instruments. Therefore, chemists are constantly improving the method of sample pretreatment to make it simpler, faster, more accurate and more efficient. Solid-phase extraction technology is a sample pretreatment technology developed by combining liquid-solid extraction and liquid chromatography. It uses selective adsorption and selective elution to separate, purify and enrich samples. It is simple and fast, simplifies the steps of sample pretreatment, shortens the processing time, has strong selectivity, reduces the amount of solvent used, reduces environmental pollution and cost, and has been developed to...
