2 lamp was calibrated by Optronics with an absolute accuracy traceable to National Institute of Standards and Technology (NIST) of ±10%. A NIST-calibrated VUV photodiode was used to calibrate the vacuum monochromator and to measure the absolute VUV flux emitted by the argon flashlamp. This system was also used to monitor the ozone concentration during the photolysis experiment from λ = 250 nm absorption measurements.

note
-
We used NIST SRM standards to calibrate the QMS system in accordance with the same comparative protocol widely adopted in gas chromatography. No detailed knowledge of the molecular, electron, or photon beam was required in this approach. However, careful control of the flow rate, pressure differentials, and other variables was essential to achieve a high precision in the cross-calibration and in the photolysis experiment.
