Tubing and Retention Gaps

Deactivated tubing can be used as guard columns or transfer lines. Our standard deactivation process is a phenyl methyl deactivation – the preferred choice for most applications due to its inertness and robustness. Undeactivated tubing, or bare fused silica, is commonly used for capillary electrophoresis. It can also be used for transfer lines and other applications where inertness is not critical. Retention gaps are used to improve peak shapes for some types of samples, columns, and GC conditions. They are available in several polarities.
