Ammonia Gas Cylinders

Yes. All ammonia calibration gas mixtures from SpecGas Inc. are NIST-traceable standards, produced under rigorous quality protocols using state-of-the-art equipment. NIST traceability ensures that the certified concentration values are directly tied to national measurement standards, supporting accurate, auditable, and defensible calibration results for regulatory and research applications.

Ammonia calibration gas is available in disposable steel cylinders (17–103 liter gas capacity), disposable aluminum cylinders (58 liter capacity for reactive gases), high-pressure refillable aluminum or steel cylinders, and nickel-plated cylinders. Disposable cylinders are particularly well-suited for field applications and overseas transport due to their portability and shipping compliance.

Nitrogen and air are the standard balance gases used in ammonia calibration gas mixtures. SpecGas Inc. also offers custom balance gas options to meet specific application requirements. Customers should specify their preferred balance gas when requesting a quote, especially if the application involves compatibility with particular analytical instruments or process environments.

SpecGas Inc. uses a proprietary internal cylinder treatment process specifically developed for reactive gas mixtures like ammonia. This treatment conditions the cylinder walls to prevent NH₃ adsorption, which is a primary cause of concentration drift. The result is a stable, accurate mixture with an extended shelf life — a critical advantage for reactive gases that are notoriously difficult to maintain at certified concentrations.

Ammonia calibration gas cylinders are widely used in environmental and air quality monitoring, industrial manufacturing process control, research and university laboratories, gas detector and analyzer calibration, and emissions monitoring programs. SpecGas serves independent labs, OEM manufacturers, utilities, power generation facilities, and major gas distributors requiring reliable reactive gas standards for ongoing compliance and quality assurance.

Yes. SpecGas Inc. offers custom ammonia gas mixture specifications tailored to unique concentration requirements, cylinder sizes, and balance gas preferences. Technical consultation is available for complex specialty gas blend requests. With all blending performed in-house by experienced specialty gas chemists, SpecGas can accommodate non-standard requirements that larger suppliers are typically unable or unwilling to produce.
