An experimental study has been conducted of effects of materials, spectrum, surface/volume ratio (S/V) and cleaning technique on the photochemical reactions observed in a smog chamber. A unique chamber and lighting system was used, which permitted independent variation in chamber materials and in light conditions. The study included four materials-aluminum, Pyrex, Teflon, and stainless steel, and two conditions each of spectrum, S/V, and cleaning. A complete factorial testing sequence was performed.
