SpecGas Inc. offers Hydrogen Sulfide (H₂S) calibration gas in PPB-level concentrations for precise detector calibration and environmental monitoring. Custom blends from 300 ppb to 10% volume are available in disposable and refillable cylinders, backed by NIST-traceable standards and a proprietary cylinder treatment process for extended shelf life.
Most people can detect the characteristic rotten egg odor of H₂S at concentrations as low as 0.5 to 10 ppb. However, odor detection thresholds vary significantly between individuals. Importantly, at higher concentrations H₂S causes olfactory fatigue — meaning the smell disappears even as dangerous levels persist, making instrument-based monitoring essential for reliable safety.
