How to Select a Capillary GC Column

Dec 13 2012 Read 6651 Times

An optimised chromatographic separation begins with the column. Selection of the proper capillary column for any application should be based on four significant factors: polarity of the stationary phase, column I.D., film thickness, and column length.

At Supelco (USA), the team of GC application scientists and technical experts has created a valuable map to help you navigate through capillary column selection. Supelco’s GC Column Selection Guide meticulously escorts you through each of the deciding factors, while providing you with literature references and column selection charts grouped by industry, phase, and application. Also included is a detailed description of each Supelco capillary phase, including chiral phases, and a handy cross reference chart for comparing Supelco column chemistries to those from other manufacturers.
