Gas chromatographic behaviour of carbohydrate trimethylsilyl ethers: I. Aldopentoses
TLDR
In this paper, the four components of each aldopentose were separated as O-trimethylsilyl ethers on several packed and capillary columns, and a mathematical approach was applied which tried to relate structural characteristics with retention indices on several stationary phases.About:

TL;DR: The detection of ribose provides plausible insights into the chemical processes that could lead to formation of biologically relevant molecules in suitable planetary environments and suggests that the generation of numerous sugar molecules, including the aldopentose ribose, may be possible from photochemical and thermal treatment of cosmic ices in the late stages of the solar nebula.

Capillary gas-chromatographic analysis of monosaccharides: improvements and comparisons using trifluoroacetylation and trimethylsilylation of sugar O-benzyl- and O-methyl-oximes.
TL;DR: Two new procedures for the gas-chromatographic analysis of monosaccharides are reported, which probably provides the best resolution achieved to date of the C3-C6 aldoses, as well as of the corresponding alditols.
