Carbon layer open tubular capillary columns

Abstract

SummaryCapillary columns coated with Carbopack materials, which provide separation by a mixed partition/adsorption mechanism or by adsorption alone, have recently been developed. The reproducibility of the columns is demonstrated and applications shown in which they provide separations which are either unique or are faster than can be achieved with the wall coated open tubular capillary columns currently available.

“…Since the plot of this relationship is a straight line for each compound, differences in the slope of the line imply differences in column polarity. We used this relationship successfully to compare the polarity of cyanosiloxane capillary columns when determining the equivalent chain length values for fatty acid methyl esters [23].…”
