Abstract
The invention provides a pretreatment device for detection of dihydroxybenzene substances and an application. The pretreatment device comprises a plastic tube (1), a sampling needle (2), a sampling needle cylinder (3), a water absorbing material (4), a water absorbing material tube (5) with a hole in bottom, a conical plastic tube cap (6), a water absorbing material tube cap (7) a sampling needle pushing rod (8) and a water removal agent (9), wherein the sampling needle (2), the sampling needle cylinder (3) and the sampling needle pushing rod (8) constitute a sampler; the water absorbing material (4), the water absorbing material tube (5) with the hole in the bottom and the water absorbing material tube cap (7) constitute a temporary saliva storage; the plastic tube (1) and the conical plastic tube cap (6) constitute a closed centrifuge tube. The pretreatment device can be applied to detection of the dihydroxybenzene substances such as catechol, resorcinol, hydroquinone and the like in saliva simultaneously and has the advantages of being rapid, accurate, simple to operate and the like.
Description
technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a pretreatment device specially used for detecting quinone substances in saliva and its application. Background technique [0002] Hydroquinone refers to a compound with two hydroxyl groups (-OH) attached to the benzene ring, mainly referring to catechol, resorcinol and hydroquinone. Catechol, also known as 1,2-benzenediol, is an important intermediate in the pharmaceutical industry. It is used to prepare berberine, isoproterenol and other drugs. It is also an important basic organic chemical raw material. It is widely used in the production of dyes, photostable Agents, photosensitive materials, spices, preservatives, accelerators, special inks, electroplating materials, lacquer flame retardants, which emit toxic and corrosive odors under high heat, can cause poisoning through the skin, and have a stimulating effect on the central nervous system and the r...
