MEGA manufactures Gas Chromatrography capillary columns in Italy since 1980.

His founder, Mario Galli, has more than 50 years of experience in Gas Chromatography technique, both in analytical and instrumentation development fields. He has been cooperating side-by-side with Professor Kurt Grob since the pioneering age of capillary GC to develop the procedures of surface inertness and coating of both glass and fused silica  capillary columns.

Over the years our research and development activity has been, and still is, constantly focused towards the improvement of the existing products as well as the development and introduction of brand new ones.

Today MEGA offers one of the most complete range of GC columns, the quality of which is guaranteed by testing each column one-by-one using the Grob Test mixture to ensure the high efficiency of our products, and also other dedicated Test mixes for special and custom columns. Our catalog includes GC-MS low bleeding columns, FAST-GC columns and solutions for Multidimensional and GCxGC Comprehensive techniques.

Moreover MEGA produces the most efficient GC columns with cyclodextrines-based stationary phases for enantiomeric chiral separations (MEGA-DEX columns line).

We offer the possibility to completely customize the product, realizing ad-hoc special columns to solve your specific analytical problem. We test your sample for you.

Our range of products is completed with PRESS-FIT connectors (2-ways union, 3-ways “Y” type and 4, 5-multiways type) and a Retention-Gaps line deactivated for any purpose.

We constantly offer our experience and innovation in order to find the right solution for your GC analysis.
