Abstract
The chromatographic characterization of two diol stationary phases for HPLC prepared via a hydride intermediate followed by hydrosilation is described. The bonded materials are the result of the reaction of 7-octene-1,2-diol or allyl glycidyl ether with silica hydride. Characterization in the reverse phase mode was done via a standard mixture of three polycyclic aromatic hydrocarbons (PAHs). In the normal phase mode, retention data of model compounds in several different eluents were compared to each other and with data available from the literature. ESCA analysis is used to monitor for the presence of reduced Pt catalyst and when it is detected its effects can be seen in the chromatographic data.
