GB/T 6682 Analytical laboratory water specifications and test methods3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Derivative derivatization The target compound which is difficult to detect in the sample is quantitatively converted into a compound which is easy to detect by a chemical reaction, and the latter can be detected by the latter. Qualitative and/or quantitative analysis of the target compound. 3.2 Purine derivatives hydrazonederivatives The carbonyl-containing compound component reacts with 2,4-dinitrophenylhydrazine (hereinafter referred to as DNPH) under the action of a strong acid to form a stable Compound.4 Method summaryThe carbonyl-containing compound component of the sample reacts with DNPH under strong acid to form a stable colored quinone derivative, which is highly efficient. Determination of anthraquinone derivatives by liquid chromatography, using retention time characterization and peak area quantification to obtain the aldehyde/ketone substance content in the sample The chemical reaction equation is as follows. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 37196-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 37196-2018_English as soon as possible, and keep you informed of the progress.
