Yes. SpecGas specializes in custom hydrogen gas blends at very low PPM and sub-PPM PPB concentration levels. Mixtures are blended in-house to exact customer specifications using NIST-traceable methods, with a proprietary cylinder treatment process to maintain blend stability and accuracy throughout the cylinder's service life and shelf period.

SpecGas offers H2 gas cylinders ranging from 17 liters to 2,000 liters in gas phase volume. Cylinder types include disposable steel and aluminum, as well as refillable high-pressure aluminum, steel, and nickel-plated options. Carbon Composite Type 3 configurations are available for high-pressure hydrogen storage with reduced overall cylinder weight.

Yes. All hydrogen calibration gas mixtures produced by SpecGas Inc. are NIST traceable and certified to both national and international standards. This traceability ensures the accuracy and reliability required for gas detector calibration, analytical instrument verification, research laboratory applications, and compliance with OSHA calibration guidelines.

SpecGas serves a wide range of industries including research and university laboratories, semiconductor and electronics manufacturing, industrial process control, gas detector calibration, emissions monitoring, power generation, and laser applications.
