Abstract
It has been found that considerable amounts of nitrosamines may be formed as artifacts during the analysis of rubber nipples by a method that involves Soxhlet extraction of the samples with dichloromethane. The extent of such formation was monitored by incorporating morpholine as a marker amine and studying the formation of nitrosomorpholine, which varied between 9 and 80 ng per analysis depending on the type of sample analysed and the brand of dichloromethane used. The problem could be minimised by pre-testing dichloromethane for its N-nitrosation potential and by incorporating propyl gallate, an N-nitrosation inhibitor, in the method.
