摘要
食品接触材料的迁移量检测是保障食品安全的重要手段。本文研究了基于气相色谱-质谱联用（GC-MS）技术的迁移量检测方法，并对该方法进行了验证与不确定度评定。通过对不同类型食品接触材料的迁移物质进行提取与分析，验证了GC-MS在定性、定量分析中的准确性与稳定性。采用不确定度评定方法分析了测试过程中的各类误差来源，为食品接触材料迁移量检测提供了可靠的技术支持和理论依据。研究结果表明，GC-MS方法不仅能够高效检测迁移物质，还能提供精确的定量数据。

Abstract
Migration quantification of food contact materials serves as a critical measure for ensuring food safety. This study investigates a migration detection method utilizing gas chromatography-mass spectrometry (GC-MS), with comprehensive validation and uncertainty assessment conducted. Through extraction and analysis of migrating substances from various food contact materials, the method's accuracy and stability in both qualitative and quantitative analysis were validated. The uncertainty evaluation methodology was applied to identify error sources during testing, providing reliable technical support and theoretical foundation for migration quantification. Results demonstrate that GC-MS not only enables efficient detection of migrating substances but also delivers precise quantitative data.
Key words： Food contact materials; Migration quantification; GC-MS; Method validation; Uncertainty assessment
