Ozone is collected indirectly on fiberglass treated with nitrite.  The ozone reacts with the nitrite ion (NO2) to form a nitrate ion (NO3).  The filter is then extracted with deionized water and analyzed for nitrate by ion chromatography.  A low instrument reporting limit is made possible by using a ultra pure source of nitrite.
