Calibration gas mixture requirements are becoming increasingly
demanding as analytical instruments become more sophisticated
and accurate. Air Products has a wealth of experience in producing
a wide range of such mixtures. Locally-held stocks of the most
frequently used mixtures, supported by fast and cost-effective
production of individual mixtures, ensure the highest level of
service.
State-of-the-Art Mixture Filling
All our mixtures are filled using the most accurate and cost-effective
technology. For most applications our filling systems use gravimetric
filling (component addition by weight) on high precision weighing
scales. This precise instrumentation and our technical expertise
ensure that the rigorous tolerance requirements are always fulfilled.
Mixtures Traceability
Due to our thorough approach to quality, we are able to trace
every mixture back to its original filling data. This data includes
cylinder numbers, actual components weights and chromatographic
and spectroscopic analysis results. In addition, Air Products
supplies mixtures fully traceable to international reference standards,
such as NPL (UK), NMi (Netherlands)and NIST (USA).
