Derivatization is a technique used in chemistry which converts a chemical compound into a product (the reaction's derivate) of similar chemical structure, called a derivative. Generally, a specific functional group of the compound participates in the derivatization reaction and transforms the educt to a derivate of deviating reactivity ...

衍生化是一种利用化学变换把化合物转化成与其类似化学结构的过程。一般来说，一个特定功能的化合物参与衍生反应，溶解度，沸点，熔点， 聚集态 或化学成分会产生偏离。 由此产生的新的 化学性质 可用于量化或分离。 样品 的衍生化的作用主要是把难于分析的物质转化为与其化学结构相 …

2023年8月29日 · This process whereby a molecule is chemically altered to enhance its detection by a particular analytical method is called derivatization. 7

Derivatization involves changing in some way the basic chemical or physical structure of a compound, usually to a single product, which may be more useful for the analysis of the original analyte in liquid chromatography (LC). Derivatization …

Derivatization is a chemical reaction between an unknown amount of analyte(s) in a sample and a reagent, of which the amount can be varied. From: Carbohydrate Analysis by Modern Liquid Phase Separation Techniques (Second Edition), 2021

Derivatization is one of the most widely used sample pretreatment techniques in Analytical Chemistry and Chemical Analysis. Reagent-based or reagent-less schemes offer improved detectability of target compounds, modification of the chromatographic properties and/or the stabilization of sensitive compounds until analysis.

2018年12月5日 · derivatization is involved in the analysis, this can be done with a non-labeled reagent for the analytes in the sample, while the internal standards are obtained by derivatization of...

2023年1月1日 · Derivatization is the process by which an organic compound is reacted with a reagent, or reagents, to yield products suitable for analyses by various techniques.

2018年12月5日 · The first part of this chapter presents the main objectives for performing derivatization of a sample to be analyzed by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). The derivatization is typically done to change the analyte properties for a better separation and also for enhancing the method sensitivity.

Derivatization is a useful tool allowing the use of GC and GC/MS to be done on samples that would otherwise not be possible in various areas of chemistry such as medical, forensic, and envi-
