In every institution or commercial organisation, concepts like safety, efficiency, reliability and precision are part of the development of systems that guarantee the quality of the product.
The gas industry plays a vital role in the metrological chain, producing several patterns that are used in the calibration and verification of instruments and equipment.
In the production process of a calibration gas mixture, Linde uses the most reliable reference materials from international entities like NIST (National Institute of Standards and Technology, US), the VSL (Van Swinden Laboratorium, formerly NMi, NL) and the NPL (National Physical Laboratory, GB).
In addition to this, Linde takes part in the progress of the chemical metrology of gases and participates in discussions forums as well as organizing inter-laboratory tests. These additional tests assure the trustworthiness of the analysis beyond the equipment and / or the analysts involved.
