Helium's long reign as the preferred GC carrier gas is ending. Facing persistent global shortages and rising costs, labs are turning to hydrogen，an alternative that's significantly easier and cheaper to obtain.

Hydrogen's ultra-low viscosity allows much higher optimal linear velocities (~40-50 cm/s vs. helium's 25-30 cm/s). This means sharper peaks, better resolution, and analysis times reduced by up to 40%, boosting lab throughput dramatically.

Operated at its optimal speed (van Deemter curve minimum), hydrogen delivers separation efficiency matching or even surpassing helium in many applications.

This is hydrogen's game-changer. Unlike helium, dependent on scarce resources and volatile supply chains, hydrogen is primarily sourced from water. Modern hydrogen generators use water electrolysis to produce ultra-pure (>99.9999%) H₂ on-demand, right in your lab. This eliminates expensive cylinder deliveries, logistics hassles, and price shocks. One generator investment provides continuous, stable supply – you control it.

When powered by renewables, hydrogen generation is a clean process, supporting greener lab operations.

Modern hydrogen generators prioritize safety with features like automatic shutdown, leak detection, and minimal gas storage. Properly installed and used, they pose minimal risk.

High-quality generators consistently deliver ultra-high purity hydrogen, ensuring stable baselines and meeting stringent requirements, even for sensitive detectors like MS.

Hydrogen is successfully used across GC applications: environmental (VOCs), food safety (pesticides, flavors), petrochemicals, pharma, and forensics. Its adoption is rapidly growing.
