Accredited Mixtures

High-precision weights for standard weight measurements

For your complete peace of mind our range of Experis® specialty gases include calibration mixtures certified by our own state-of-the-art ISO 17025 accredited laboratory. This means that they meet the most stringent demands for accurate and traceable calibration suitable for a range of markets and applications. The direct traceability to internationally recognized standards and reference materials from National Metrological Institutes is an additional guarantee of quality.

Air Products’ comprehensive ISO 17025 accreditation scope is optimized to serve our customers in the environmental monitoring sector. It is now possible to source calibration gas mixtures containing all of the components NO, SO₂, CO and CO₂ in the same cylinder, certified by an ISO 17025 accredited calibration laboratory. This provides users with a number of important technical, safety, and cost benefits over more commonly available binary gas mixtures.

Extensive Scope

For engine emissions testing, air emissions monitoring, and natural gas composition analysis.

Unique Capabilities

Able to supply calibration gas mixtures containing all of the components NO, SO₂, CO and CO₂ in a single cylinder.

Technical Benefits Of Multi-Component Mixtures

Calibration using binary mixtures can lead to errors in the analysis of stack gases due to cross-sensitivity effects

Improved Safety And Storage

Using accredited multi-component mixtures means you can reduce the number of cylinders you handle and store by as much as 75%

Reduced Gas Control Equipment Inventory

Fewer cylinders means results in less set-up time on site, and a smaller gas control equipment inventory

Cost Savings

Multi-component mixtures can reduce your costs, when compared to purchasing cylinders of individual binary mixtures
