Ultra High Purity Grade Hydrogen

The purest form of hydrogen is ultra high purity (UHP) grade hydrogen, typically specified at 99.999% purity or higher. For calibration and analytical applications, precision blends are further refined to exact PPM or PPB concentrations, NIST-traceable to national standards. SpecGas produces custom hydrogen blends down to sub-PPM and PPB levels for the most demanding research and instrumentation requirements.

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. 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.

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.

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.

SpecGas ultra high purity hydrogen serves four primary industries: Research & Laboratory, where it supports GC calibration, FTIR analysis, and equipment accuracy verification; Semiconductor & Electronics Manufacturing, where precision blends enable critical process control; Industrial Process & Manufacturing, where stable custom blends support precision production processes; and Laser & Photonics, where UHP hydrogen is used in excimer and other laser systems where gas purity directly affects beam quality and output consistency.
