SCOT 毛细管GC色谱柱

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.

Supelco 是支撑涂层开管（Support Coated Open Tubular, SCOT）色谱技术的领导者。我们卓越的制造技术使得我们可在不锈钢管的内壁上独特的涂覆一层液相涂层支持颗粒。这项技术使我们能够获得传统熔融石英毛细管柱制造技术无法实现的许多相。SCOT 色谱柱将毛细管气相色谱的灵敏度和良好的样品分辨率与广泛的填充气相色谱固定相库相结合。

我们所有的 SCOT 柱的尺寸为 50 英尺 x 1/32 英寸外径 x 0.02 英寸内径，每端包括 1/16 英寸外径连接。它们采用3.5英寸的线圈进行捆扎并在两端均带有12英寸的松散柱。四款色谱柱均有现货库存。带有其他相的色谱柱可通过我们的定制项目获取。

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.
