摘　　要：稳定同位素质谱法(Stable Isotope Ratio Mass Spectrometry,IRMS)是一种质谱技术,专注于测量样品(如食品)中的碳、氮和氢等元素的稳定同位素比率。通过分析食品样品中特定元素的稳定同位素组成,IRMS能够追踪食品的来源并验证其真实性。本文通过介绍稳定同位素质谱技术的原理、技术分类,并分析其在食品掺假检测和产品溯源中的应用,旨在为检验人员和监管部门提供技术指导和理论支持。Stable isotope ratio mass spectrometry(IRMS)is a mass spectrometry technique that focuses on measuring the stable isotope ratios of elements such as carbon,nitrogen,and hydrogen in samples(such as food).By analyzing the stable isotope composition of specific elements in food samples,IRMS can track the source of food and verify its authenticity.This article introduces the principle and technical classification of stable isotope mass spectrometry technology,and analyzes its application in food adulteration detection and product traceability,aiming to provide technical guidance and theoretical support for inspectors and regulatory authorities.
