Abstract

A new polar polysiloxane stationary phase for capillary column gas chromatography containing 4‐(methylsulfonyl)phenyl substitution was synthesized and compared to a cyanophenylpolysiloxane, OV‐225. The sulfonylphenylpolysiloxane phase was useful and stable over a wide temperature range from 70°C to 320°C, and it exhibited similar overall polarity to OV‐225. However, because of the specific chemical properties of the 4‐(methylsulfonyl)phenyl group, this phase demonstrated unique selectivities for certain classes of compounds including basic nitrogen heterocycles and polychlorinated biphenyls.
