General description

Application: This column, for detailed analyses of petroleum products, is known within the petroleum and chemical industries for its unique selectivity. Baseline separations of benzene/1-methylcyclopentene and toluene/2,3,3-trimethylpentane that are possible with this column are not obtainable with classical poly(dimethyl siloxane) columns.
USP Code: None
• Bonded
• Poly(50% n-octyl/50% methyl siloxane)
Temp. Limits:
• -60 °C to 220 °C (isothermal or programmed)

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
