β¦ Synopsis
Pyrocarbon is a generic term for a variety of allotropic modifications of carbon which can be distinguished from other carbonaceous allotropes, such as diamond and soot, by the fact that they are hard, black, and strong. Some properties, which are pertinent to the present communication, are listed in Table 1.

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
A new simplified method was developed for the preparation of immobilized stationary phase fused silica capillary columns coated with OV-1-vinyl, SE-54, and OV-1701 -vinyl. This methodology includes the application of the moderately polar stationary phase OV-1701 -vinyl as a surface deactivation agen
The activity of fused silica capillary tubing has been shown to vary considerably, which severely influences the reproducibility of column deactivation and inertness. Methods for producing a reproducible, high activity surface with maximum hydroxylation by various hydrothermal treatments were evalua
