β¦ Synopsis
Sugars were separated gas chromatographically on short apolar glass capillary columns by using cold, on-column injection (OCI) techniques. After silylation, oligomers up to the hexasaccharides could be efficiently separated in reasonable retention times. Response factors of silylated sugars were determined as a function of varying sample amounts anld concentrations. The optimum injection amount was found to be 1 pl in heptane as solvent.
