## Abstract As an alternative to acid pretreated UCON and FFAP capillaries for the analysis of wide‐boiling free fatty acid mixtures, OV‐1 : FFAP phase mixtures were used on high‐temperature silylated inert glass capillary columns. The HETP‐carrier gas velocity curves, peak asymmetry factors, coati

In this report we describe the coating of deionized glass surfaces with commercially available CH,O-terminated diphenyl-dimethylpolysiloxane (PS-OSO).This newtype of reactive, high temperature stable stationary phases withstands temperatures up to 430°C.As already reported for OH-terminated polymers
