A multifunctional test sample extraction and separation device

Abstract

The invention provides a multifunctional inspection sample extraction and separation device adopting an integrated device. A main body is composed of four parts including a reaction device, an extraction device, a retractable groove and a liquid storage device, and sealing, fixing and filtering accessories with simple structures are arranged; all contact inspection samples are made of high-temperature-resisting, high-pressure-resisting and toxin-free materials; and a PTFE (polytetrafluoroethylene) lining layer on a contact surface between the reaction device and an inspection sample has a capability of resisting strong acids (strong alkalis). According to testing requirements, all physical and chemical treatment processes including digestion and degradation, chemical derivation, impurity (effective component) adsorption or sedimentation, liquid or solid separation and the like can be finished, or a plurality of types of physical and chemical treatment processes can be finished according to actual requirements. Compared with an existing extraction and separation technology or device, the multifunctional inspection sample extraction and separation device provided by the invention has remarkable progresses in the aspects of usage diversity and operation convenience and in the aspects of reducing analysis errors and saving occupied spaces of tools, and can overcome the disadvantages of a conventional method.

Description

Technical field [0001] The invention relates to the technical field of chemical analysis instruments, in particular to a multifunctional test sample extraction and separation device, which is suitable for the detection of pretreatment operations such as digestion, purification and separation of nucleotides and base samples in biochemical products, and is also suitable for other needs Perform preparation or detection and analysis operations for solid-liquid separation. Background technique [0002] Nucleotides and bases are rich in purines. Excessive intake of humans will induce diseases such as gout and hyperuricemia, which will seriously affect the health of kidneys, bones and joints. However, currently, some food and beverage companies randomly add guanylic acid and inosinic acid (I+G), yeast extracts, seafood extracts and other high-purine substances to foods in order to improve the taste and umami taste, resulting in purines in foods. The content is elevated and is not detai...

AI Technical Summary

Problems solved by technology

However, in the existing conventional separation technology, each pretreatment method can only use the corresponding equipment, such as digestion and degradation, chemical derivatization operations generally use digestion tubes, derivation tubes, impurities (active ingredients) adsorption or precipitation use beakers, flasks or reaction devices; separation operations using funnels, filters, centrifuges, etc.

These conventional utensils have single functions. When dealing with a large number of samples or complicated steps, a large number of utensils need to be used and cleaned after use, the utensils occupy the working space, the operation is cumbersome, and residual liquid loss or improper sample dilution occurs during the transfer process. and many other problems, resulting in defects or deficiencies such as high intensity of detection work, low efficiency, and large detection errors.
