✦ Synopsis

Electroformed nickel tubing was deactivated by chemical vapor deposition of silicon from silane gas and subsequent treatment with cyclooctamethyltetrasiloxane (D4). Standard activity tests performed on the uncoated tube and also on columns coated with crosslinked and uncrosslinked, nonpolar stationary phase, show that good quality flexible columns can be prepared from nickel tubing. The inner surface of the silicon coated tube was characterized by Auger depth profile analysis.

A new polymer, polymethacryloxypropylhydrosiloxane PMAHS , has been developed and used as both a deactivating layer and an intermediate layer for stable coating of an uncharged polymer on fused silica capillaries in capillary electrophoresis. The deactivation procedure is based on a siliconhydride d
