Title The measuring and monitoring of formaldehyde in inhalation test atmospheres
Bibliographic information Feb. 1983, Vol.44, No.2, p.71-77. Illus. 12 ref.
Abstract Two procedures for the determination of formaldehyde concentrations in animal testing inhalation chambers, using chromotropic acid, were evaluated. In the first, the chromogen was mixed with sulfuric acid prior to use, and in the second, the reagents were added sequentially. The 2nd procedure gave more reliable results. Collection of airborne samples of formaldehyde in impingers containing 1% aqueous sodium bisulfite provided more stable storage conditions than collection in water alone. When shipping samples, great care must be exercised to avoid contamination with materials commonly used for sample bottle caps and seals that can cause interferences.
