A new tobacco filler Standard Reference Material (SRM) has been issued by the National Institute of Standards and Technology (NIST) in September 2016 with certified and reference mass fraction values for nicotine, N-nitrosonornicotine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone, and volatiles. The constituents have been determined by multiple analytical methods with measurements at NIST and at the Centers for Disease Control and Prevention, and with confirmatory measurements by commercial laboratories. This effort highlights the development of the first SRM for reduced nicotine and reduced tobacco-specific nitrosamines with certified values for composition.
2016 年 9 月,美国国家标准与技术研究院(NIST)发布了一种新的烟草填充料标准参考物质(SRM),其中包含尼古丁、N-亚硝基降烟碱、4-(甲基亚硝氨基)-1-(3-吡啶基)-1-丁酮和挥发性物质的经认证和参考质量分数值。这些成分已经通过多种分析方法确定,测量工作分别在 NIST 和疾病控制与预防中心进行,并由商业实验室进行了确认性测量。这一努力突出了第一个用于降低尼古丁和降低烟草特异性亚硝胺的 SRM 的开发,该 SRM 的成分具有经认证的数值。
