State-of-the-art CALYPSO Nitrogen Generators for LC-MS (MS)

Any LC-MS (Liquid Chromatography Mass Spectrometry) requires a reliable source of Nitrogen gas and to meet the specific market demands, F-DGSi’s very first gas generator that was manufactured was a Nitrogen generator. With more than 15 years of experience, our CALYPSO range has become the benchmark. Thanks to the robust architecture and stable operation helping the various manufacturers LC-MS to run continuously 24/7.

CALYPSO gas generators are available in two technologies: PSA and membrane. These nitrogen gas generators utilize advanced technology to ensure reliable and continuous nitrogen gas generation, thus meeting the strictest requirements for purity and sensitivity. With flow rates of up to 70 L/min, purities of up to 99.5%, and pressures of up to 8 bar (116 psi), CALYPSO offers unmatched performance and versatility.


Why a gas generator? The benefits of gas generator?

Provide your laboratory with a reliable and easy-to-use gas solution on demand. A gas generator is the practical and economical alternative to pressurized gas cylinders, dewars or bulk storage of laboratory gases. A gas generator provides on-demand gas at the push of a button to meet your needs instantly and efficiently, but not only that, there are also these benefits:



No cylinder changes


The gas purity is constant - no need to add extra gas filters


No gas contract administration, low and stable ongoing gas cost


Removes the risk of leaks, need for long gas lines from cylinders


Can be located either on the bench or on the floor next to your GC instrument


No repeated gas deliveries, energy efficient
