Ultra High Purity Grade Hydrogen

Ultra high purity hydrogen refers to hydrogen gas with extremely low levels of contaminants, typically 99.999% (5.0 grade) purity or greater. It is used in applications where even trace impurities can compromise results, including gas chromatography, semiconductor fabrication, laser systems, and precision laboratory research. SpecGas formulates UHP hydrogen calibration blends traceable to NIST standards for verified accuracy.

UHP hydrogen is required in gas chromatography calibration, FTIR and moisture analyzer calibration, semiconductor and electronics manufacturing, excimer and other laser applications, and research laboratory processes. Any process where trace impurities or concentration inaccuracies would skew analytical results or damage sensitive equipment demands UHP-grade hydrogen with documented purity traceability.

Yes. All hydrogen gas blends produced by SpecGas Inc. are NIST traceable and certified to national and international standards. This ensures each mixture meets the accuracy and documentation requirements needed for regulatory compliance, equipment calibration, and quality assurance programs in research, industrial, and semiconductor environments.

Yes. SpecGas specializes in custom hydrogen blends formulated to exact customer specifications at both PPM and PPB concentration levels. Using proprietary in-house blending techniques and internal cylinder treatment processes, SpecGas delivers stable, precise hydrogen mixtures tailored to your instrument calibration or process control requirements, with competitive lead times and quality guarantees.

SpecGas offers ultra high purity hydrogen in disposable steel and aluminum cylinders as well as refillable high-pressure aluminum, steel, and nickel-plated cylinders. Gas phase volumes range from 17 liters to 2,000 liters, accommodating both short-term laboratory use and larger industrial or ongoing calibration program needs.

The SpecGas Stability Guarantee is a commitment that reactive gas mixtures, including hydrogen blends, will maintain their stated concentration and stability for their certified shelf life. This is achieved through SpecGas's proprietary internal cylinder treatment process. If a mixture is disputed, SpecGas conducts a re-analysis and investigation and provides an immediate remake and re-ship at no cost.
