**F-DGSi** is a French, family-owned manufacturer founded in 2006 and headquartered near Paris. The company designs and produces a wide range of high-purity gas and liquid generators—such as hydrogen, nitrogen, and liquid nitrogen systems—for laboratory and industrial applications.

## History

F-DGSi was created by its current CEO Fabienne Palgé in 2006 in Les Ulis, France.[1]

- 2011 - F-DGSi expands in India and the United Arab Emirates
- 2012 - Nitrogen generators are added to The Alliance range - revealed at the PITTCON event (Florida).
- 2014 - IGSM (Innovative Gas System Manufacturing) division is created
- 2015 - Distributor agreements signed in South Africa, Russia, the United States and Japan
- 2017 - F-DGSi launches its range of liquid nitrogen generator, the CRYOGEN
- 2018 - F-DGSi Inc opened in Boston, United States
- 2019 - The COSMOS and CALYPSO ranges are revealed to replace the Alliance ranges. Revealed during the Forum Labo show in Paris
- 2023 - F-DGSi India Pvt. Ltd. opened in India

## Products

The company manufactures a variety of on-site gas generation systems aimed at replacing high-pressure cylinders:

- **Hydrogen generators (COSMOS series)**, producing hydrogen with purities up to 99.99999% for GC/GC-MS applications.[2]
- **Nitrogen generators**, for LC-MS, GC×GC, and sample evaporation, using membrane and PSA (Pressure Swing Adsorption) technologies.
- **Zero air generators**, supplying purified air for analytical detectors such as FID, often as part of modular COSMOS stacks.[3]
- **Liquid nitrogen generators (CRYOGEN series)**, producing 10–80 L/day of cryogenic liquid nitrogen on-site using PSA separation and liquefaction technology.[4]

## Manufacturing and quality

All research, design, and manufacturing are carried out at the company's Paris-area facility. Products are developed to ISO-compliant standards, with reliability and safety as priorities. The company also provides proactive remote monitoring and long-term service contracts through its "F-DGSi Care" program.[5]

## Applications

F-DGSi generators are used in laboratories and industries for techniques such as gas chromatography (GC), liquid chromatography–mass spectrometry (LC-MS), inductively coupled plasma (ICP), total organic carbon (TOC) analysis, nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC), rheology, and particle sizing.

## Awards

- The G3+ rating by the Bank of France, a certificate awarded as a safe company with international customers (2014)
- Grant issued by the French government with a €250,000 prize to promote and develop F-DGSi's product innovation internationally (2014)[6]
- The Export and Innovation prize awarded by the Ile de France Regional Council for an exceptional international performance (2014)[7]
