基于电感耦合等离子质谱法的蟹黄中重金属含量不确定度评定研究

Evaluation of Uncertainty in Heavy metal Content in Crab Roe Based on Inductively Coupled Plasma Mass Spectrometry

为确保蟹黄产品的质量安全,建立了一种快速检测重金属元素的方法,采用电感耦合等离子体质谱法,通过优化样品前处理和仪器分析条件,实现了对多种元素的高灵敏度和良好精确度的同时检测。该方法回收率和检出限符合标准要求,并通过不确定度评定,确保测定值的精确可靠性。

In order to ensure the quality and safety of crab roe products,we studied and established a rapid detection method of heavy metal elements,using inductively coupled plasma mass spectrometry,and by optimizing the sample pretreatment and instrument analysis conditions,to achieve high sensitivity and good accuracy of multiple elements at the same time detection.Methods The recovery rate and detection limit meet the requirements of the standard,and the uncertainty evaluation ensures the accurate reliability of the measured values.
