gas metrology - calibrations

Calibrations of secondary standard ozone analysers

For those Member State NMIs that do not hold primary standards for ozone in air, the BIPM offers calibrations of secondary standard ozone analysers.

Interested laboratories are invited to contact Dr J. Viallon for the relevant calibration request forms.

 

Calibration service: Ozone photometers

Matrix or material Analyte or component Dissemination range of measurement capability
Amount-of-substance fraction x(O3) / (nmol/mol) Absolute expanded uncertainty (k = 2) / (nmol/mol)
synthetic air ozone 0 to 1000 2 Q[0.52, 0.0034 x(O3), 0.0106 x(O3)]
  1. The notation Q[a, b] stands for the root-sum-square of the terms between brackets
  2. The claimed uncertainty includes a term coming from the best device under test
  3. Absolute expanded uncertainty: k = 2, level of confidence 95%
