Helium Calibration Gas

Yes. All helium calibration gas supplied by SpecGas Inc. is NIST traceable, meaning the concentrations and purity levels are certified against national standards maintained by the National Institute of Standards and Technology. This traceability ensures measurement accuracy and supports compliance with ISO 17025 and other quality frameworks.

SpecGas offers helium calibration gas in cylinder sizes ranging from 17 liters to 2000 liters gas phase volume. Available cylinder types include disposable steel, disposable aluminum, high-pressure aluminum, high-pressure steel, and high-pressure nickel-plated cylinders. A cylinder deposit program is also available to reduce ownership costs.

Yes. SpecGas specializes in custom multi-component gas blends using gravimetric blending with proprietary techniques. Helium can serve as a balance gas or active component in mixtures alongside VOCs, reactive gases, nitrogen, air, and other specialty gases, with concentrations achievable down to PPB levels.

Helium calibration gas serves semiconductor and electronics manufacturing, excimer and helium-neon laser applications, research and university laboratories, photolithography processes, gas chromatography and analytical instrument calibration, and industrial process control. It is also used in solar panel manufacturing, flat-panel display production, and OEM instrument manufacturing.

SpecGas employs a proprietary internal cylinder treatment process developed through decades of specialty gas R&D. This treatment conditions the cylinder walls before filling, minimizing reactive surface interactions and ensuring the helium mixture remains accurate and stable throughout its shelf life, even in demanding reactive blend applications.

SpecGas Inc. blends all mixtures in-house and maintains industry-leading lead times. Standard orders are processed quickly, and rush service is available upon request. Customers needing urgent supply for calibration deadlines or unplanned instrument maintenance can contact SpecGas directly at (215) 443-2600 to discuss expedited options.
