The capacity for non-polar stationary phases of the silanized inner surfaces of glass capillary columns is shown to be restricted to a 2-3 x IO-' m thick film. However, geometrical modification of a soda-glass surface by etching with NC1 gas before silanization allows non-polar silicone-oil films to

For a typical narrow bore (50 pm) and wide bore (320 Fm) capillary column the effects of increased stationary phase film thickness (df) on the minimum detectable amount, Q, , as well as on the minimum analyte concentration, C , , are described. In treating the effect of an increased film thickness,
## Abstract Four poly(methyl 3,3,3‐trifluoropropyl siloxanes) with trifluoro‐propyl group content (group substitution) between 8 and 35 percent have been synthesized and characterized as stationary phases for gas chromatography in borosilicate glass capillary columns. Results are compared with thos
