9 检测的N-亚硝胺的确定
9.1 通过下列步骤之一确定已检测的N-亚硝胺及其含量:
a)取一个干净的、可透紫外光的玻璃容器，装入部分剩余试验溶液，用波长为366nm的紫外光照射试样3h;取另一相似的玻璃容器，按同样方法处理标准溶液(5.9)。由于N-亚硝胺受紫外光照射会分解，气相色谱分析可能不显示峰或者只显示已明显衰减的峰。如果样品经照射后，信号衰减不明显，则表明原始信号被错误确认。在这种情况下，没必要进行下一步测定。

Condoms — Determination of nitrosamines migrating from natural rubber latex condoms
9.1 The determined N-nitrosamines and their quantities need to be confirmed according to one of thefollowing procedures:
a)by irradiating one aliquot of the remaining test solution in a clear, UV permeable glass vessel with UVlight (3 h, wave length: 366 nm). Treat a standard solution (5.9) produced in the same way in a secondvessel analogously. Owing to the decomposition, the CG analysis might show either no peaks or onlyremarkably diminished peaks for N-nitrosamines. The original signals were wrongly positive if the signalsfrom the samples are not remarkably diminished after the irradiation. In this case, a further test for thedetermination of N-nitrosamines is not necessary
