When used at considerably higher temperatures – and working without septum purge – interfering peaks can occur due to thermal decomposition of the material.

Retention Gaps

The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column.
Choice of the retention gap depends on the solvent used:
Me-Sil retention gap Only for use with n-hexane and diethyl ether
Phe-Sil retention gap for all solvents except methanol and water
CW retention gap for all solvents and especially for methanol and water
Me-Sil retention gaps are more inert than Phe-Sil, while Phe-Sil is less susceptible to contamination.
Retention Gaps Available 10mtr & 25mtr
Methyl-Sil deactivated (max. temperature 320 °C) 0.25 mm ID (0.4 mm OD)
Phenyl-Sil deactivated (max. temperature 320 °C) 0.32 mm ID (0.5 mm OD)
CW deactivated (max. temperature 25 °C) 0.53 mm ID (0.8 mm OD)
PRE Columns (Deactivated Capillary Columns)
Recommended application: for preparation of capillary columns as precolumn, whenever a larger contamination capacity is required.
Pre Columns Available 10mtr & 25mtr
Methyl-Sil deactivated (max. temperature 320 °C) 0.25 mm ID (0.4 mm OD)
Phenyl-Sil deactivated (max. temperature 320 °C) 0.32 mm ID (0.5 mm OD)
CW deactivated (max. temperature 25 °C) 0.53 mm ID (0.8 mm OD)
