Hydrogen Cyanide (HCN) Calibration Gas

HCN calibration gas is available balanced in nitrogen, air, or other inert gases based on your application needs. Custom balance gas selection is offered to ensure compatibility with your specific gas detector, analyzer, or process instrument calibration requirements.

SpecGas uses a proprietary internal cylinder treatment process developed through decades of specialty gas R&D. This unique treatment passivates the cylinder walls, preventing reactive HCN molecules from degrading, and significantly extends the shelf life and accuracy of each blend compared to standard cylinders.

HCN calibration gas is available in specially-treated aluminum cylinders and nickel-plated cylinders, with internal water volumes ranging from 5.9L to 47L. Disposable aluminum cylinders are also offered for field use, remote operations, and applications requiring transport between locations.

Yes. All HCN calibration gas blends produced by SpecGas Inc. are NIST-traceable standards, ensuring uncompromising accuracy and compliance with industry calibration requirements. NIST traceability is fundamental to SpecGas's quality process and is maintained across every concentration and cylinder size offered.

HCN calibration gas is used across workplace safety monitoring, chemical manufacturing (plastics, acrylic fibers, rubber), agriculture (fumigants and pesticides), mining (sodium cyanide precursor for gold and silver extraction), pharmaceuticals (antihypertensive drugs), and metallurgy (steel case hardening and metal cleaning processes).

HCN is classified as a systemic poison and extremely toxic hydracid. OSHA exposure limits and CDC safety guidelines must be strictly followed. Proper ventilation, gas detection equipment, and personal protective equipment are required in any workplace handling HCN. Always verify your HCN gas detector is correctly calibrated before entering potentially exposed environments.
