Agilent VF-5ms GC Columns
The VF-5ms is a highly inert 5% phenyl-methyl column for increased sensitivity, accuracy and instrument uptime. The columns have the lowest guaranteed bleed specification of 1 pA @ 325 °C (30 m, 0.25 mm, 0.25 µm). VF-5ms has a slightly higher polarity than the VF-1ms resulting in a better selectivity for aromatic compounds. This selectivity, combined with superior inertness, also makes these columns applicable for a wide range of semi-polar and even polar components, such as phenols.
