Completely customize your column by selecting every combination of sizes and asking for out-ofcatalog confgurations. Since 1980 we develop ad-hoc solutions for your specifc analytical problem.We are also able to tune the selectivity of the stationary phase to respond to particular needs.
All our stationary phases are available for FAST, Conventional,Wide-Bore and Multidimensional-GC, including solutions and kits for GCxGC.
Products Highlight

Built-in Retention Gap - No Connections needed
MEGA-GAP columns line incoroporates both guard column and analytical column in a continuous length of tubing, eliminating the connection and all connection-associated problems. The guard column side is permanently marked with our oven temperature resistant labels.
Original Large Volume Gaps (UNCORET) columns (0.53mm, 12m Integrated Gap + 3m coated) are available from MEGA.
Extend your column's lifetime with this connection-free solution!
Easy to handle - Excellent inertness - Easy to install
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 precut pieces individually packaged and ready to use. By request we also pre-install (with our Press-Fit connectors, see below) the selected retention gap on the GC column for a ready-to-install solution.
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 confgurations.
Easy to handle - Easy to install A simple pressure to assure a perfect seal
MEGA Press-Fit Connectors allow you to simply connect, with a tight seal, different columns or Retenetion Gaps in many ways. Our Press-Fit connectors are universal to ft any tubing size. Available as linear 2-ways union (to connect two columns or a Retention Gap to the analytical column), "Y" 3-ways (e.g. ideal to connect two columns to a single injector - double detector GC confguration) or personalized Multiwas connectors for advanced analytical system confgurations as MD-GC and other custom settings.

GCxGC Solutions
MEGA offers unique and innovative products for your GCxGC analysis.
We can provide completely custom GCxGC solutions, including readyto-use kits.
The selectivity of the stationary phase plays a fundamental role in GC and it is even more important in GCxGC. Ask us to tune the selectivity of the stationary phase thus to explore new and unique solutions and to optimize the orthogonality and the effciency of your GCxGC confguration.
