Abstract

The invention relates to a method for determining organic residual, which comprises detecting the unprocessed big hole adsorption resin, and preconditioning the big hole adsorption resin, the detecting method is used under the special chromatographic condition, an internal marker method and an outer marker method are used to proceed the example quantitative determination and residual quantity calculation. The advantages of the method by the invention are, the sample is easy for treatment, the detection is quick and sensitive, each type of organic residual can be detected from the sample.

Description

Technical field: [0001] The invention relates to a method for detecting organic residues, in particular to a method for detecting organic residues in macroporous adsorption resins, medicines and foods. Background technique: [0002] Macroporous adsorption resin is a kind of high molecular polymer developed in the 1940s, and has been widely used in environmental protection, chemical industry, medicine and food industries. In recent years, macroporous adsorption resin has been widely used in the enrichment and purification of active ingredients in traditional Chinese medicine and natural medicine extracts, which is of great significance to the modernization of traditional Chinese medicine. However, all resins currently on the market are chemical resins, which contain organic residues such as benzene, toluene, xylene, styrene, diethylbenzene, divinylbenzene, naphthalene and alkanes; Macroporous adsorption resins are used in the production process, and organic residues in the m...
