Calibration Gases & Mixtures
Define the mixture for your measurement task.
The useful specification connects composition, concentration, uncertainty, packaging and the instrument's operating requirements.
Start with the application
A mixture is more than a gas name.
Tell us what you need to calibrate or verify: the instrument, measurement range, sample matrix and target components. This provides the basis for reviewing a suitable mixture and its documentation.
The cylinders shown here illustrate a packaged calibration-gas shipment. Their appearance does not identify the composition, concentration or certification of the contents.

What to include in your enquiry
A specification or instrument method is a useful starting point. If a requirement is not yet defined, identify it for technical review.
Package & quantity
- Total quantity and number of cylinders
- Cylinder water capacity and ownership
- Fill pressure and reference temperature
- Valve outlet and connection requirements
Documents & delivery
- Required stability period and storage conditions
- Certificate content and traceability requirements
- Destination and named Incoterm place
- Required delivery date and repeat demand
Documentation is mixture-specific. Feasibility, stability, analytical method, uncertainty and traceability are confirmed for the agreed composition and package. A certified reference material or accredited certificate must be explicitly requested and confirmed; neither is implied for every mixture.
The safety document register contains product-specific references. Request the applicable SDS for the actual mixture; a pure-gas SDS is not a substitute.
