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.
Application Notes
Visit our applications webpage to discover hundreds application notes and to fnd useful information on how to develop your analytical method. New technical notes are constantly added.
PRESS-AT connectors
MEGA Press-Fit connectors allow you to simply connect, with a tight seal, different columns or Retention Gaps together in many ways. Our Press-Fit connectors are custom-made to fit any tubing size and to ensure the minimal dead volume. Visit our website to download the free guide “Press-Fit Connectors Tips” and discover how easy is to use our Press-Fit connectors.
Press-Fit Unio linear connectors, ideal to connect two columns or a Retention Gap to the analytical column.
Press-Fit “Y” three ways connectors, ideal to connect two analytical columns to a single injector port or split the exit of one column to a dual detector GC system. Many other configurations are possible using MEGA “Y” Press-Fit.
MEGA produces also personalized Multiways Press-Fit connectors for advanced analytical system configurations as MDGC and other custom settings.
General Purpose RETENTION GAPs
Retention Gaps deactivated for any purpose : our Retention Gaps are suitable for any analytical needs (use with polar solvents, apolar solvents and for general use) and 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.). Any length is available, also in pre-cut pieces individually packaged and ready to use. We also offer specific deactivation for aqueous samples injections.
MEGA Retention Gaps have an unsurpassed chemical inertness. Use our Retention Gaps for focusing the sample components when introducing a large (liquid) sample directly into the column and/or to protect the analytical column from contamination. Retention Gaps are also useful as connecting pipes to various part of systems with different configurations.
Discover also our MEGA-GAP columns line with integrated built-in Retention Gap. No connections needed. Visit our website or contact us for more information. Original Large Volume Injection UNCORET columns (0.53mm, 12m Gap + 3m coated) available.
