The deviations were well within the errors of the measurements however, when comparing the data with the DOAS instrument systematically higher values were found with the LOPAP instrument. The validation of the instrument was performed in the laboratory for HONO concentrations of 3 and 30 ppbV using ion chromatography and with a DOAS ( differential optical absorption spectrometer) instrument in a large outdoor smog chamber in the range from 0.1 to 20 ppbV. The accuracy of the measurements is in the range between ±(10−15)%. Detection limits ranging from approximately 3 to 50 pptV have been obtained with response times from 4 to 1.5 min, respectively, using different instrument parameters. Laboratory investigations were carried out to characterize the instrument components with respect to collection efficiency, optimum dye formation, optimum detection, and interfering species. in smog chambers, in exhaust gases, and in indoor environments. This instrument is aimed to overcome the known problems with current HONO measurement techniques and was designed to be a cheap, sensitive, compact, and continuously working HONO monitor for ambient air measurements in the troposphere or for measurements of higher concentrations e.g. A new in situ instrument (LOPAP: long path absorption photometer) to measure gaseous nitrous acid (HONO) using wet chemical sampling and photometric detection has been developed.
