Determination of five soluble sugars in tea by gas chromatography hydrogen flame ionization

Determination of 5 soluble sugars in tea by gas chromatography hydrogen flame ionization Details:



This document specifies the gas chromatographic analysis method for detecting five soluble sugars in Guizhou tea (see Appendix A).

This document is applicable to the gas chromatographic analysis of fructose, glucose, sorbitol, inositol and sucrose in tea in GUI state by hydrogen flame photometric detector.

Name: capillary column



Stationary phase: 5% phenyl-95% dimethyl polysiloxane



Specification: 60m * 0.25mm * 0.25um



Model: HH-5

Application: GUI state tea soluble sugar detection gas chromatography hydrogen flame ionization method



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has established a method for the detection of five soluble sugars in tea through experiments. The sample is determined by silylation reaction, gas chromatography hydrogen flame ionization method, and quantitative method is internal standard method. The recovery rate of five soluble sugars in this method is 81.74%~100.55%, the relative standard deviation is 2.04%~9.49%, and the detection limit is 9.5~12.2 ng · mL - 1. This method has high recovery rate and good precision, It is a simple, rapid and practical method for the determination of soluble sugar in tea
