OV® Capillary Columns
OV® Capillary Columns ensure very reproducible results with low bleed, high thermal stability and high theoretical plate counts.
The first liquid phase with a silicone design for use as a gas chromatographic stationary phase (OV-1) was introduced in 1966. Since then OV has continued to develop and manufacture the most complete line of liquid phases available. They have modified their phases with a variation of functional groups to achieve a wide polarity range.

Here is the list of liquid phases available in Capillary columns:
OV®-1 (100% dimethylpolysiloxane)
OV-1 capillary columns are bonded and crosslinked. They are a non-polar dimethylsilicone capillary column with an operating temperature range from -60C to 330/350C. OV-1 applications include amines, flavors, fragrances, hydrocarbons, PCBs, pesticides, and phenols. The OV-1 Phase is equivalent to USP G2.
