Rapid Method for the Detection and Quantification of N-Nitrosodibutylamine in Rubber Products

Abstract
A rapid method for the detection and quantification of N-nitrosodibutylamine (NDBA) migrating from rubber products into a neutral buffer solution is described. The extraction, clean up, and concentration is done by a onestep procedure using C18 cartridges. NDBA in the ppb range is identified and quantitated by gas chromatography (GC) with a thermal energy analyzer (TEA) as detector.
