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).
