摘要:

液相色谱-同位素比质谱(LC-IRMS)是一种特征化合物同位素分析技术,该技术利用LC IsoLink接口设备实现液相色谱与同位素比质谱的联用,通过检测目标物质的稳定碳同位素比(δ13C),实现样品的产地来源与品质真实性鉴定。该文总结了IRMS与LC-IRMS技术的概况,以及过去20年LC-IRMS的发展历程;归纳整理了LC-IRMS在食品安全、生态与环境、生命科学及考古学等领域的应用情况;评述了LC-IRMS面临的技术局限、挑战及其未来的发展趋势。

Abstract:

The first commercial interface for hyphenating liquid chromatography with isotope ratio mass spectrometry (LC-IRMS) was not available until 2004, and it was commercialized under the name LC IsoLink by Thermo Finnigan. LC-IRMS, a method of compound-specific isotope analysis, has enabled the detection of stable carbon isotope ratios (δ13C) in targeted substances in order to determine their origin and authenticity. This paper provides an overview of IRMS and LC-IRMS techniques, the history and detailed classification of the latter over the past twenty years. The application of LC-IRMS to the fields of food safety, environment and ecology, life sciences, and archeology are reviewed. Finally, the technical limitations, current challenges, and future development trends of LC-IRMS are outlined.
