TLDR
This article showed that the absence of a C6 methoxyl group lowers the response of a flame ionization detector, and that the presence of C6 methyl glucopyranosides lowers the detection performance.Abstract:
Carbowax 20M treated with 2-nitroterephthalic acid used as the liquid phase for gas-liquid chromatography gives sharply resolved peaks for several partially and fully methylated methyl glucopyranosides. The detector response of the standard compounds shows that the absence of a C6 methoxyl group lowers the response of a flame ionization detector.read more

Determination of the structure of a broth dextran produced by a cariogenic streptococcus
TL;DR: The broth polysaccharide from the cariogenic bacterium Streptococcus mutans E49 has been shown by periodate oxidation and methylation studies to be a highly branched dextran and a modification of the sodium hydride-methyl iodide method of methylation is presented.
