Gas generation for your laboratory
Explore F-DGSi hydrogen, nitrogen, zero air and liquid nitrogen generators through SAMSI. On-site generation can reduce cylinder handling and help provide a consistent gas supply close to your analytical instruments.
Explore the product range
CALYPSO — Nitrogen for LC-MS
Nitrogen generators for LC-MS and LC-MS/MS. The range includes PSA and membrane technologies, with configurations for single or multiple gas streams. Select a model to match your instrument’s flow, pressure and purity requirements.
COSMOS — Modular gas solutions
Stackable hydrogen, nitrogen, zero air and compressor modules create a compact gas supply for GC laboratories. Build a combination for carrier gas, detector gas, make-up gas and sample preparation.
COSMOS — Hydrogen generators
Produce hydrogen on demand from deionised water. The MF.H2 range is designed for high-purity carrier gas applications; MD.H2 and MB.H2 options serve detector fuel gas needs. Touchscreen control and leak monitoring support daily operation.
COSMOS N2 / ZN2 — Nitrogen
Compact PSA nitrogen generators for GC make-up gas, suitable carrier gas applications, headspace pressurisation and thermal desorption tube conditioning. Stack with other COSMOS modules to create an integrated supply.
COSMOS RACK ZA — Zero air
Convert a suitable compressed air supply into zero air using catalytic purification and filtration. Designed to reduce hydrocarbon contamination in detector air for GC applications.
Z.PROSPERO — Nitrogen & air
Combined high-purity nitrogen and purified air in one cabinet for GC carrier gas, make-up gas and detector air. Models are available with or without an integrated oil-free compressor, with touchscreen control and remote diagnostics.
CRYOGEN — Liquid nitrogen
Generate liquid nitrogen on site from ambient air for laboratory and cryogenic applications. The CRYOGEN range combines nitrogen generation, liquefaction and a built-in dewar, with touchscreen monitoring and dispensing through an insulated hose.
Select the right gas supply
Tell SAMSI your instrument manufacturer and model, required gases, operating pressure, flow rate and purity. We can help select a generator and assess whether an integrated compressor or additional gas treatment is needed.
For a GC carrier gas change, the choice of gas and generator must also suit the instrument, detector and analytical method.
