SpecGas Inc. Hydrogen Cyanide (HCN) Calibration Gas provides NIST-traceable, precisely blended HCN mixtures ranging from 100 ppb to 10% concentration. Supplied in specially-treated aluminum cylinders for extended shelf life, these gases serve gas detector calibration, industrial manufacturing, mining, agriculture, pharmaceutical, and metallurgical applications.


OSHA has established exposure limits for Hydrogen Cyanide (HCN) that must be strictly followed in any workplace where HCN is present. Along with CDC safety guidelines, these limits require proper ventilation, calibrated gas detection equipment, and appropriate personal protective equipment (PPE). Always ensure your HCN gas detector is correctly calibrated before entering potentially exposed environments to remain compliant with OSHA standards.

HCN calibration gas used to verify and calibrate toxic gas detectors and monitoring instruments in industrial workplaces.

HCN serves as an intermediate chemical in the production of plastics, acrylic fibers, rubber, dyes, and paints.

HCN is a precursor to sodium cyanide used in gold and silver extraction, electroplating, and steel case hardening.

HCN is used in antihypertensive drug synthesis, PMMA biomaterials, and as an agricultural fumigant and pesticide ingredient.
