质谱峰匹配法测定肉制品中四种挥发性N—亚硝基化合物含量
Determination of Trace Volatile N—Nitrosocompounds in Meat Products by GC and Peak Matching Technique
【摘要】 N-亚硝基化合物是公认的强致癌物质。我们曾于1981年研究和比较了四种质谱定量方法。本文采用其中一种方法即高分辨峰匹配技术测定了炒肉片、炸肉段、酱肉、熏肉、香肠共43份样品中四种 N—亚硝基化合物的含量,并对其结果进行了讨论和评价。
【Abstract】 N-nitrosocompounds are intense carcinogens,we studied and compared four kinds of MS methods for the determination of them in 1981:(1) low resclution EI SIM;(2)high resolution EI peak matching;(3) low resolution CI SIM;(4) high resolution CI peak matching.The method described here is based cnabove methods using bigh resolution peak matching technique which can be used to determine N-nitrosocomponnds in 43 samples of meat products.The results were discussed and estimated.
