Calibration Services
We recommend that all of our instruments be calibrated at least once annually. The calibration includes cleaning of the entire flow path (inlet, solenoid valve(s), detection cell, DewLine™ and connecting tubing) with methanol, installation of new internal scrubber(s) and particle filter(s), and calibration to a NIST-traceable standard. In addition, all instrument components are tested for performance (lamp intensity and precision, flow rate, etc.) and any problems diagnosed. Be sure to return your instruments for calibration and testing prior to your next field experiment.
Ozone monitor calibration: Our ozone transfer standard is a Thermo Electron 49i Primary Standard ozone calibrator. This instrument was most recently calibrated at the National Institute for Standards and Technology (NIST) in Gaithersburg, Maryland, on February 8, 2022.

NOx monitor calibration: The calibration of all 2B Technologies NO2/NO/NOx Monitors™ is traceable to NIST through a Working Standard for ozone. A NIST-traceable concentration of ozone is reacted quantitatively with a standing concentration of NO in a gas phase titration (GPT) according to the reaction: NO + O3 -> NO2 + O2. The depletion of NO measured by the NO2/NO/NOx Monitor provides the calibration for NO. The calibration is traceable to NIST via the same Thermo Electron 49i Primary Standard ozone calibrator.
