Device and method for quickly detecting integrated chemical reaction

Abstract

The invention relates to a device and method for quickly detecting an integrated chemical reaction, and relates to the technical field of quick detection of food, drugs, cosmetics and the like. The detection device is a cylindrical or circular cone-shaped sealed cavity, and consists of a sealed cover (1), a pretreatment chamber (2), a reaction chamber (3), a filter pipe (4), a pretreatment reagent (5) and a reaction reagent (6), wherein the sealed cover (1) is arranged at the top of the pretreatment chamber (2); the pretreatment chamber (2) is vertically communicated with the reaction chamber (3) through the filter pipe (4); a microporous filter element or other filter material (4.1) is mounted inside the filter pipe (4); the pretreatment reagent (5) is placed in the treatment chamber (2) or other containers in advance; the reaction reagent (6) is placed in the reaction chamber (6) in advance, or is frozen and dried, or is prepared into tablets or pills, or is added from a side hole (3.1). The detection method comprises the following steps: putting a sample in the pretreatment chamber (2), or adding the pretreatment reagent (5), sealing the cover, shaking, centrifuging, reacting, observing or detecting the result. The sample pretreatment, filtering and reaction integration are realized, and the method is simple, convenient and practical; standardization is easily realized; the detection device is suitable for rapid field detection.

Description

technical field [0001] The invention relates to an integrated rapid chemical reaction detection device and its method; in particular, it relates to an integrated rapid chemical reaction detection device and method for rapid detection of food, medicine and cosmetics, etc., belonging to the technical field of rapid detection. Background technique [0002] In the field of rapid detection technologies such as food, medicine and cosmetics, various rapid detection technologies including chemistry, microscopy, chromatography, spectroscopy, immunity, and biology have been developed and applied. The most common method is the traditional chemical detection method, mainly because The chemical detection method has good specificity, low cost, and simple operation. Many kinds of fast chemical detection methods have been established in China. Usually, this method needs to pretreat the sample, filter it, and then react with a specific reagent in the actual application process. At least thre...

AI Technical Summary

Problems solved by technology

Usually, this method needs to pretreat the sample, filter it, and then react with a specific reagent in the actual application process. At least three steps are required, so the operation is not very convenient. Certain poisonous or easy to pollute the environment, especially the above defects are more obvious when operating on site

At the same time, it is difficult to standardize the operation

[0003] In short, the common quick chemical detection method has certain defects, and it is not convenient to use
