Abstract
An ethylene-using ozone chemiluminescence meter produces 1.3 moles of formaldehyde per mole of ozone over ozone concentrations of 0.040 to 0.45 ppm. The formaldehyde was quantitated by a variation of the West-Gaeke technique for sulfur dioxide, and is specific for formaldehyde. The constancy of the stoichiometry allows formaldehyde collection to be the basis of a new calibration technique for the meter.
