Rapid method for the detection and quantification of N-nitrosodibutylamine in rubber products.
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 one-step 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.
