Linde offers various different types of Specialty Gas Mixtures. To deliver exactly what the customer wants, a common understanding of what tolerances are is crucial. Find out how different demands on purity come together.
1. Requested concentration (nominal concentration): The component concentration the customer requests (e.g. 2,0% Carbon Monoxide in air mixture)
2. Blend tolerance: The level of agreement between the blended concentration and the nominal concentration (e.g. blending tolerance of +/- 5%)
3. Analytical Results: The reported level of the nominal concentration based on laboratory analysis (e.g. 2,05%)
4. Analytical Uncertainty: The level of agreement between the blended concentration and the nominal concentration (e.g. analytical uncertainty of +/- 2%)
The following graph summarises the different levels:
