The Fused Silica Tubing
We produce all of our GC capillary columns from fused silica. Our tubing can withstand temperatures of over 425°C. However, the polyimide coating and liquid phase are what limits the high temperature end of the column. Our deactivated tubing is excellent to use as guard columns or retention gap columns.
The Stationary Phase
In 1966, we introduced OV-1, which is our first silicone designed for use as a gas chromatographic stationary phase. Since then, we have continued to develop and manufacture, exclusively for gas chromatography, the most complete line of liquid phases available. We have also modified our phases to achieve a wide polarity range.
Bonding and Conditioning
All OV® columns are bonded and cross linked. We condition each column to achieve excellent thermal stability. We use conditioning techniques that give excellent thermal stability and allow a long lifetime for the column.
Each OV® capillary column is tested individually. We do not batch test columns. We are happy to consider “special testing” with your sample on our column. Please contact us for information on this service.
