Hydrogen Sulfide (H2S) — High Purity Gas

You can get hydrogen sulfide (H2S) calibration gas from SpecGas Inc. by submitting an online quote request or calling (215) 443-2600. SpecGas produces custom concentration blends from 300 ppb to 10% volume in disposable and refillable cylinders, and ships domestically and internationally to support field and laboratory applications.

Yes. H2S gas can be purchased as a precision calibration standard from SpecGas Inc. Available in concentrations from 300 ppb to 10% volume, cylinders come in disposable aluminum, disposable steel, refillable aluminum or steel, and nickel-plated options. Pricing is available on request, and custom blends can be produced to your exact specification.

SpecGas Inc. offers H2S calibration gas from 300 ppb (sub-ppm) up to 10% by volume. This broad range covers PPB-level, low PPM (1–100 ppm), and mid-PPM to percent concentrations, making these blends suitable for environmental monitoring, detector calibration, and industrial process applications requiring varying sensitivity levels.

H2S is available in disposable aluminum cylinders, disposable steel cylinders, refillable aluminum or steel cylinders, and nickel-plated cylinders. Gas phase volumes range from 17 liters to 2,000 liters, supporting everything from portable field bump testing to extended laboratory or industrial use where larger volumes are required.

Yes. All H2S calibration gas standards produced by SpecGas Inc. are NIST traceable, manufactured using state-of-the-art blending equipment and analytical verification processes. NIST traceability ensures your gas standard meets national accuracy benchmarks, which is essential for compliance-driven applications in environmental monitoring, occupational safety programs, and industrial calibration requirements.

SpecGas uses a proprietary internal cylinder treatment process specifically developed for reactive gas mixtures like H2S. This treatment minimizes wall reactions and concentration drift, resulting in an extended shelf life compared to standard industry cylinders. A SpecGas Stability Guarantee backs all reactive gas mixtures, ensuring your calibration standard remains accurate throughout its intended service period.

SpecGas H2S calibration gas serves a wide range of industries including petrochemical and oil and gas (detector calibration and refinery process monitoring), environmental and wastewater monitoring (calibrating H2S monitors at treatment plants and emissions stations), research and laboratory settings (analytical instrument calibration and organosulfur compound synthesis), and agriculture and industrial manufacturing (monitoring in fertilizer pits, biodigesters, textile manufacturing, and pulp and paper processing).
