GL Sciences Fused Silica Tubing

GL Sciences deactivated fused silica tubing can be used as a guard column or retention gap, and for other applications. Retention gaps are used to improve peak shapes for some types of samples, columns, and GC conditions.

Guard Columns: Injecting samples with contaminants or non-volatile compounds directly onto a column causes active sites and/or degradation of the stationary phase. With the use of on-column and splitless injections, and even with split injection, contamination and degradation of the columns are an unavoidable problem. To protect an analytical column from such damages, it is effective to connect a 2m fused silica deactivated capillary tubing to the inlet of the column, and replace the tubing as the contaminants gets accumulated.

Retention Gap Columns: Retention gaps help focus the compounds in large volumes injected from the inlet to a tight band at the head of the analytical column in order to reduce peak broadening. The silica capillary tube can be used as a retention gap by connecting the silica capillary tube to the entrance of the separation column for about 2m.

Deactivated Fused Silica: As fused silica is relatively inert structure, in general usage there are no analytical problem. However, sometimes tailing or adsorption occur when analysing polar samples, by the influence of siloxane bridges and silanols remaining in the inner of column. GL Sciences offer our original inertness technology of deactivated fused silica capillary tubing, showing strong inertness to polar samples.

Deactivated fused silica capillary tubing shows strong inertness to polar samples.

The silica capillary tube is well suited to most solvents other than water by internal surface treatment and has no holding power against solutes.

Tubing can be used as a transfer line for GC/MS, LC/MS, GC/FTIR, LC/GC, Multi‐Dimensional GC, or sniffer adaptors.
