| Abstract: | For analysis of a bunch of samples,a rapid,selective,sensitive and precision method in EN 12868:1999 was developed to determine the release of N-nitrosamines and N-nitrosatable substances from elastomer or rubber teats and soothers in both of sample preparation and instrumental analysis.To imitate the migration of N-nitrosamines and N-nitrosatable substances from rubber balloons and teats to human body,rubber products studied in this research were soaked in artificial saliva.The target analytes released to ... |
