Fused silica, desirable properties

In addition to providing highly selective separations, there are a multitude of other desired characteristics that a gas chromatographic stationary phase should possess. These properties include high viscosity, low surface tension allowing for wetting of the fused silica capillary wall, high thermal stability, and low vapor pressure at elevated temperatures. The stationary phase solvent should also not exhibit unusual mass transfer behavior. [Pg.149]

SILICA, FUSED. (Quartz.) The desired property of this material is its low coefficient of thermal expansion. It is primarily used in refractories for kiln and furnace walls, and as a shell material for molds in... [Pg.781]
