Retention Gaps (deactivated tubing)

Retention Gaps deactivated for any purpose: our Retention Gaps are suitable for any GC analytical need. Use with polar solvents, apolar solvents, water containing samples injections and for general use. They are available in any internal diameter size (0.05, 0.075, 0.10, 0.15, 0.18, 0.20, 0.25, 0.32, 0,45 and 0,53mm I.D.) with our standard fused silica tubing or with our High-Temperature fused silica tubing. Any length available, also in pre- cut pieces individually packaged and ready to use. By request we also pre-install the selected retention gap on the GC column for a ready-to-install solution.

Easy to handle – Excellent inertness – Easy to install


MEGA Retention Gaps have an unsurpassed chemical inertness. Use our Retention Gaps for focusing the analytes when a large (liquid) sample is introduced directly into the column and/or to protect the analytcal column from contamination. Deactivated Retention Gaps are also useful as connecting pipes to various part of GC systems with different configurations (dual detectors GC systems, Multidimensional GC, etc.).
