Custom CH4 Gas Cylinders — 10L Methane

Custom CH4 gas cylinders are available in disposable aluminum, disposable steel, refillable aluminum or steel, and nickel-plated cylinders. The appropriate cylinder type depends on your application, required shelf life, and whether the mixture is intended for field use, laboratory settings, or long-term storage.

Yes. All methane calibration gas standards produced by SpecGas Inc. are NIST traceable, meaning every blend is referenced to National Institute of Standards and Technology measurement standards. This ensures regulatory compliance and measurement confidence for calibration of gas detectors, analyzers, and monitoring equipment.

SpecGas uses nitrogen, zero air, and other inert gases as balance gases in methane mixtures, depending on the application. The choice of balance gas is important for instrument compatibility — for example, zero air balance is typically used for combustible gas detector calibration, while nitrogen balance suits many analytical and research applications.

Yes. SpecGas specializes in custom gas blending to customer specifications. Whether you need a specific concentration, balance gas, cylinder size, or multi-component mixture including methane, SpecGas can produce it in-house. Consultation with gas blending experts is available to ensure the correct mixture is delivered for your application.

Common applications include LEL combustible gas detector calibration, 4-gas confined space monitor bump testing, EPA NSPS and GHG methane emissions monitoring, natural gas BTU custody-transfer calibration, landfill and biogas plant CH4 monitoring, coal mine methane monitoring per MSHA Part 75, and LDAR (Leak Detection and Repair) program TVA calibration per EPA Method 21.

SpecGas provides a re-analysis and resolution service for disputed mixtures. If a customer disputes the stated results of a cylinder, a replacement mixture is provided immediately while the original cylinder is returned for re-analysis and a resolution discussion. This ensures confidence in every calibration gas order with no disruption to operations.
