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 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.
摘要
本文描述了一种快速检测和定量从橡胶制品迁移至中性缓冲溶液中的N-亚硝基二丁胺（NDBA）的方法。采用C18柱通过一步程序完成萃取、净化和浓缩。通过配备热能分析仪（TEA）作为检测器的气相色谱（GC）对纳克级范围内的NDBA进行鉴定和定量。
