Traditional fused silica columns are not equipped to handle prolonged exposure to temperatures above 360 °C. At high temperatures, fused silica GC columns may become:
For applications that contain high molecular weight compounds, which require temperatures above 360 °C, a high temperature GC column such as a metal column or specialty treated capillary column is used since they are best suited to resolve these compounds with minimal bleed to provide rugged performance up to 430 °C.
