5% Hydrogen Nitrogen Gas Mix Product

At atmospheric conditions and low concentrations, nitrogen and hydrogen form a stable, non-reactive blended gas. The 5% H₂ in N₂ mixture is commonly used as a safe surrogate calibration gas for hydrogen detectors, purging applications, and atmospheric control in sensitive manufacturing environments such as semiconductor fabs and battery gigafactories.

A mixture of nitrogen and hydrogen is a precisely formulated specialty gas blend where hydrogen is combined with nitrogen as the balance gas. At a 5% H₂ concentration, it is used primarily as a calibration standard for combustible gas detectors, LEL sensors, and hydrogen-specific monitors. SpecGas provides NIST-traceable H₂/N₂ blends custom-made to exact customer specifications.

SpecGas's 5% hydrogen nitrogen gas mix is NIST traceable and certified to national and international standards. It also complies with OSHA guidelines for calibration gas usage. Each cylinder comes with a certificate of analysis confirming the exact blend concentration, and SpecGas's Stability Guarantee backs the mixture for its full shelf life.

SpecGas offers the 5% H₂/N₂ mix in disposable steel or aluminum cylinders as well as refillable high-pressure aluminum, steel, or nickel-plated cylinders. Sizes range from 17 liters to 2,000 liters gas-phase volume, allowing customers to select the right format for portable detector bump testing or large-scale industrial calibration programs.

Yes. SpecGas specializes in custom gas blending at PPM and PPB concentration levels. While 5% H₂ in N₂ is a common standard, SpecGas can formulate hydrogen nitrogen blends to virtually any concentration within safe handling parameters, tailored precisely to your detector manufacturer's calibration requirements or process specifications.

The 5% hydrogen in nitrogen blend is suitable for calibrating and bump testing hydrogen-specific detectors and multi-gas monitors from leading manufacturers including MSA, Dräger, Honeywell BW, Industrial Scientific, and RKI. It is also used to calibrate LEL combustible gas detectors, electrochemical hydrogen sensors, and safety systems in fuel cell and refueling station environments.
