Fused silica capillary columns are routinely used in a broad variety of Capillary Electrophoresis (“CE”), Mass Flow Control, Flow Cytometry, Liquid Chromatography (“LC”) and Gas Chromatography (“GC”) applications ranging from protein characterization, small molecule and genetic analysis, to Proteomics, DNA sequencing and fragment analysis.
The tubing is manufactured from high purity synthetic quartz, with a protective coating of Polyimide, the most common coating material, applied to the outer surface. The Polyimide coating is responsible for the brownish, amber color of fused silica capillary columns, which may even darken after prolonged exposure to higher temperatures. The upper temperature limit of standard Polyimide coated fused silica tubing is 360⁰ C. The high temperature Polyimide coated tubing has an upper limit of 400⁰ C. The column color has no effect on the chromatographic performance of the column.
