Description

General description

Supelco is the leader in Support Coated Open Tubular (SCOT) GC column technology. Our unsurpassed manufacturing technique allows us to deposit a uniform layer of liquid phase-coated support particles on the inner wall of stainless steel tubing. This technology gives us access to many phases that are inaccessible to conventional fused silica capillary column manufacturing technology. SCOT columns combine the sensitivity and excellent sample resolution of capillary GC with the extensive stationary phase library of packed GC.

All our SCOT columns have dimensions of 50 feet x 1/32 inch O.D. x 0.02 inch I.D. and include 1/16 inch O.D. connections at each end. They are banded in 3.5 inch coils, with 12 inch loose column at each end. Four columns are available as stock items. Columns with other phases may be available through our custom program.

Capillary columns are basically of two type wall-coated open tubular (WCOT) and support-coated open tubular (SCOT). WCOT columns consist of a capillary tube, where the walls of the tube are coated with liquid stationary phase. In SCOT capillary columns, the inner wall of the capillary is lined with a thin layer of a particulate support, such as diatomaceous earth; onto this support material a thin layer of liquid stationary phase is then coated. This is an added advantage to the SCOT columns as it provides them larger surface area and thicker layer of stationary phase than WCOT columns.

Application

SCOT Capillary GC Column may be used for high resolution gas chromatography. It may also be used for the determination of nonhydroxy fatty acid composition of rat brain lipids.
