Core offering

F-DGSi designs, develops, and manufactures laboratory and industrial gas generation systems in-house in France, producing hydrogen, nitrogen, zero air, and liquid nitrogen on-site for analytical instruments, medical applications, and industrial processes. The portfolio spans the CALYPSO and COSMOS generator families, CRYOGEN liquid nitrogen units, combined N2/Air and H2/Air generators, air dryers and filters, air compressors, the Hydrogen Sensor safety device, and recurring F-DGSi Care maintenance and 4Q qualification services.

Product overview

F-DGSi is a French manufacturer that designs, develops, and builds gas and liquid generators entirely in-house. The product portfolio centers on gas generators for hydrogen, nitrogen, air, and liquid nitrogen production, complemented by air dryers, filters, compressors, and safety detection equipment. The core offerings include the COSMOS hydrogen generator series (MF.H2, MD.H2, MB.H2) for GC/GC-MS carrier and detector gas; CALYPSO and NESO nitrogen generator lines using PSA and membrane technologies for LC-MS applications; COSMOS ZA and DEIMOS zero air generators for detector gas supply; PROSPERO/Z.PROSPERO combined nitrogen/air generators as 2-in-1 solutions; and the CRYOGEN liquid nitrogen generator series for cryopreservation and medical applications. Accessories include NDL absorption dryers, NDC CO2-free air dryers, membrane dryers, air/gas filters, and COSMOS air compressors. The ecosystem is unified through common control interfaces (color touch screens, USB/RS232 connectivity), Energy Saving Technology (EST), and remote diagnostic capabilities. F-DGSi Care service plans and 4Q qualifications provide ongoing support across the entire product range.

Products and services

• Hydrogen Generators (COSMOS MF.H2, MD.H2, MB.H2 Series) Gas generators producing high-purity hydrogen through proprietary PEM (Proton Exchange Membrane) electrolysis technology for use as carrier and fuel gas in GC and GC-MS instruments. Available in standard purity (MB.H2, MD.H2) and high purity (MF.H2) models with flow rates from 110 to 1500 mL/min, using 100% titanium PEM cells.
• Nitrogen Generators (CALYPSO, NESO, Z.NESO, ZEPHYR, TELESTO, TORNADO, THEMISTO, CELENO, STREAM lines) PSA and membrane-based nitrogen gas generators producing purity up to 99.9995% for LC-MS, GC, NMR, CD spectroscopy, MP-AES, GC-2D, and other analytical instruments, with flow rates from 1 L/min to 200.3 NM3/h. Includes Z.NESO with sub-0.05 ppm THC catalyst and high-flow TORNADO for industrial use.
• Air / Zero Air Generators (COSMOS ZA, COSMOS ZA.TOTAL, DEIMOS UZA, DEIMOS UZA.TOTAL, DEIMOS TOC) Zero air generators producing hydrocarbon-free and CO2-free compressed air for GC detectors (FID, FPD, NPD). Models include standard zero air, total zero air (removing H2O, CO2, NOx, SO2), and TOC-specific versions.
• Combined Hydrogen/Air Generators Integrated systems producing both hydrogen and zero air from a single unit for GC-FID and GC-MS applications, offering a compact alternative to separate generators.
• Combined Nitrogen/Air Generators (PROSPERO, Z.PROSPERO, THEMISTO PEGA, CELENO) 2-in-1 gas solutions combining high-purity nitrogen and dry air for GC applications including carrier gas, make-up gas, and FID detectors. Z.PROSPERO includes a catalyst module for hydrocarbon-free nitrogen.
• CRYOGEN Liquid Nitrogen Generators Self-contained turnkey systems producing 10 to 240 L/day of cryogenic liquid nitrogen for laboratories and medical applications including cryopreservation, cryotherapy, IVF, gastronomy, and GC-2D. 100% manufactured in France.
• Absorption Air Dryers (NDL) Pressure swing adsorption dryers using twin-column alumina desiccant beds providing clean, dry air at -40°C pressure dew point for GC-FID, GC-ATD, NMR, and atomic absorption applications.
• CO2 Free Air Dryers (NDC) PSA-based dryers delivering clean, dry (-70°C PDP) and CO2-free (<1ppm) air for FT-IR, purge microscope, TOC, and laser applications. Six models with flow rates from 1.5 to 120 L/min.
• Membrane Air Dryers Hollow fiber membrane dryers providing -20°C dew point air for laboratory applications requiring this water specification, positioned before zero air generators.
• Air Filters and Gas Filters Three-stage DF-T filters combining sub-micro filtration, activated carbon adsorption, and high-performance particle filtration for compressed air and gas purification in laboratory applications.
• Air Compressors (COSMOS Air Compressor) Oil-free air compressors available in 110V and 230V models, designed to integrate with COSMOS generator modules for laboratories without existing compressed air infrastructure.
• Hydrogen Sensor (Safety Gas Detection) Safety device for continuous monitoring of hydrogen concentrations in GC ovens that automatically activates acoustic alarm and switches carrier gas to inert gas when H2 reaches 25-50% LEL (1-2% by volume).
• F-DGSi Care Service Plans Comprehensive maintenance, repair, and validation services for F-DGSi gas generators including 4Q qualifications (CQ/IQ/OQ/PQ) and remote support capabilities.

Broad incumbents

• Linde Gas: Linde is a global industrial gas major that also supplies on-site gas generation systems, competing with F-DGSi at the high end of the market and bundling generators with its cylinder and bulk gas supply.
• Messer Group: Messer is a privately held industrial gas producer that supplies on-site gas generation systems and specialty gases, competing with F-DGSi in European laboratory and industrial nitrogen markets.
• Air Liquide: Air Liquide offers on-site gas generation solutions alongside its industrial gas portfolio, providing an integrated alternative that smaller specialists like F-DGSi must compete against on service and financing terms.

Emerging players

• VICI DBS: VICI DBS manufactures hydrogen, nitrogen and zero air generators for GC and LC-MS laboratories, providing another specialist alternative to F-DGSi's analytical-instrument gas products.
• Nel ASA: Nel ASA manufactures PEM and alkaline hydrogen generators with industrial and laboratory applications; its hydrogen-generation technology overlaps F-DGSi's COSMOS H2 line, though Nel focuses on larger-scale energy and mobility use cases.
• Oxigraf: Oxigraf is a smaller specialist in high-purity gas generation and oxygen concentrators, addressing adjacent laboratory and medical niches that overlap with F-DGSi's CRYOGEN liquid nitrogen line.
• Generon (Ingersoll Rand): Generon produces on-site nitrogen and oxygen generators using membrane and PSA technology, competing with F-DGSi's NESO and TORNADO nitrogen product lines, particularly in industrial applications.

Direct peers

• Claind: Claind is an Italian manufacturer of nitrogen, hydrogen and zero air generators for laboratories, a European specialist with a product range and target customers closely overlapping F-DGSi's.
• Peak Scientific: Peak Scientific is a leading global manufacturer of laboratory gas generators (nitrogen, hydrogen, zero air) for LC-MS, GC and GC-MS, making it the closest direct competitor to F-DGSi across the same product categories and customer base.
• Parker Hannifin (domnick hunter / Balston): Parker's domnick hunter and Balston lines produce laboratory-grade nitrogen, hydrogen and zero air generators for analytical instruments, directly competing with F-DGSi's CALYPSO, COSMOS and DEIMOS product families.
