摘要：

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-degrees-C to 320-degrees-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.
