How to secure Hydrogen or Nitrogen supply plus Air for GC and LC-MS?

Keeping a steady, high-purity supply of Hydrogen or Nitrogen and Air is essential for your lab’s GC and LC-MS applications. F-DGSi’s multi-gases generators provide a reliable, convenient, and safer alternative to gas cylinders—securing the gas supply you need, on demand.

Our multi-gas generators are designed to supply either:

• Nitrogen and Pure Air for GC, GCxGC, MP-AES, and LC-MS applications
• Hydrogen and Zero Air for GC applications

Once installed, these generators run 24/7 and require minimal maintenance. They eliminate the need for cylinder changes, which can introduce impurities into your gas lines and interrupt workflows. With an F-DGSi generator, you ensure a consistent, high-purity, and controlled gas supply.

Combined Nitrogen/Pure Air Generators

The combined Nitrogen/Air generators use the advanced Pressure Swing Adsorption (PSA) or Membrane technology to produce Nitrogen gas with purities from 98% up to 99.9995%. A dedicated activated alumina bed purifies air, removing moisture and hydrocarbons to deliver Pure Air with hydrocarbon levels below 0.01 ppm and an air dew point to  -55°C.

Available with or without a built-in oil-free compressor, these generators offer flexibility to meet your lab’s requirements and gas demand. Internal gas storage is minimal, and the low-pressure operation adds an extra layer of safety compared to traditional high-pressure cylinders.

Combined Hydrogen/Zero Air generators

The combined Hydrogen/Air generators use exclusive PEM (Proton Exchange Membrane) cell technology built with 100% full titanium. Combined with cold dual dynamic regeneration or membrane dryer, they deliver on-demand Hydrogen gas with purity levels up to 99.99999%. Several measures ensure a safe Hydrogen generation.

The Zero Air generation delivers high purity air by using either an internal or external oil-free compressor. A multi-stage filtration process removes moisture, a platinum catalyst oxidizes hydrocarbons and carbon monoxide to below 0.05 ppm. Air is further filtered to ensure no particles enter your analytical instruments.

Features of the F-DGSi Multi-Gases Generators
