Calibration
When calibrating trace oxygen analyzers, it is not
uncommon to find a significant variance in readings attributable
to errors associated with the gas standard, the sample delivery
system, or the highly technique-dependent procedures.
Delta F has invested over one million dollars in developing proprietary
reference methods, UHP sample delivery systems, and operating methodology
to provide the most accurate, and reliable calibration possible
for every analyzer it ships. The first step in the controlled process
is the procurement of reliable Primary Standards. They are prepared
gravimetrically using Class "S" masses traceable to NIST
and bottled in non-absorbing aluminum cylinders which are carefully
purged and evacuated prior to filling. In conjunction with a proprietary
reference method that does not depend upon any single analytical
device, the Primary Standards are the basis for NIST traceable certification
of "Working Standards" used in all instrument calibrations.
Delta F manages its gas standards under a system where periodic
re-certification avoids errors induced from unstable cylinders.
Further, a calibration system can only be as effective as its weakest
link, Delta F has designed and implemented automated, state-of-the-art
UHP gas delivery systems throughout. All of this attention to detail
ensures that every Delta F analyzer arrives at your site with an
accurate calibration traceable to NIST documented by a Certificate
of Conformance.
