Precision Gas Mixture Calibration Gases

SpecGas produces all calibration gas mixtures using gravimetric blending techniques traceable to NIST (National Institute of Standards and Technology). Each mixture is analytically verified against certified reference standards, ensuring concentration accuracy required for regulatory compliance, instrument calibration, and research applications across hydrocarbon, toxic, noble, and atmospheric gas types.

Yes. SpecGas specializes in custom gas blending to exact customer specifications, including multi-component mixtures at PPM and PPB concentration levels. Customers can specify balance gas type, concentration range, cylinder size, and tolerance requirements. Expert consultation is available to help define mixture parameters for complex or unusual applications.

SpecGas supplies a broad range of precision calibration gases including hydrocarbon gases (methane, ethane, propane, isobutylene), reactive and toxic gases (H₂S, CO, SO₂, NH₃, HCN, HCl, Cl₂, NO/NOx, PH₃), noble gases (helium, argon, neon, krypton, xenon), VOC mixtures (formaldehyde, acetone, DMS, isobutylene), moisture mixtures, and atmospheric gases (nitrogen, oxygen, CO₂, SF₆).

SpecGas calibration gases support a wide range of regulatory frameworks including EPA Methods 6, 7E, 10, 18, 21, 25A, 26, and 320; 40 CFR Part 75 Acid Rain Program CEMS; EPA NSPS Subparts for methane, NOx, CO, and SO₂; OSHA PEL and NIOSH REL exposure limit verification; GPA 2261 / ASTM D1945 natural gas BTU calibration; and ISO 17025 accreditation standards for calibration laboratories.

SpecGas uses a proprietary internal cylinder treatment process developed through decades of specialty gas R&D. This treatment conditions cylinder walls to prevent reactive gas adsorption, significantly extending shelf life and maintaining concentration accuracy. The SpecGas Stability Guarantee backs every reactive gas mixture, with immediate replacement if results are disputed.

SpecGas offers calibration gas cylinders ranging from 17 liters to 250 FT³ net gas volumes (up to 2000 liters gas phase volume for certain products). Cylinder options include disposable aluminum and steel cylinders, refillable high-pressure aluminum and steel cylinders, and nickel-plated cylinders suited for reactive and corrosive gas mixtures requiring enhanced stability.

SpecGas serves a wide range of industries including environmental and emissions monitoring (CEMS, EPA Method stack testing, ambient air quality networks), semiconductor and electronics manufacturing (excimer laser gas mixtures, photolithography, process gas calibration), oil, gas, and petrochemical facilities (LEL detection, BTU custody transfer, LDAR programs), and research and laboratory settings (GC, FTIR, GC-MS, and other analytical instruments).
