Sugars gas-liquid chromatography

Gas — liquid chromatography has proved a useful analytical technique in carbohydrate chemistry, particularly for methyl ethers and acetic esters. By forming trimethylsilyl ethers of relatively nonvolatile sulfonates of sugars, gas — liquid chromatography can be performed. [Pg.254]

The purpose of the experiment is to illustrate the application of derivatisation in the analysis of sugar and related substances by gas-liquid chromatography. The silylation method described is an almost universal derivatisation procedure for carbohydrate analysis by GC.79... [Pg.250]

The present article is concerned with the use of gas-liquid chromatography for neutral, basic, and acidic sugars and some of their simple derivatives. A succeeding article will treat the separation of methylated sugars and their derivatives. [Pg.13]

Some workers have performed hydrolyses in an autoclave, but it has been shown that 0.5 M sulfuric acid at 120° degrades 33% of L-arabinose and 22% of D-galactose in two hours.75 Such methods are, therefore, only suitable for qualitative analyses, unless accurate corrections are made. Similarly, 90% formic acid has been found76 to decompose 48% of D-xylose and 36% of D-galactose in 20 hours at 100°. Gas-liquid chromatography has been used to examine the products formed by the acid degradation of sugars.77... [Pg.20]
