亲水作用色谱串联质谱同时检测食品接触产品中三聚氰胺和三聚氰酸单体迁移量
Simultaneous Determination of Melamine and Cyanuric Acid in Food Contact Packaging Materials by Hydrophilic Liquid Chromatography-Tandem Mass Spectrometry
摘要
Abstract
An HILC-MS/MS method was developed to simultaneously determine melamine and cyanuric acid in food contact packaging materials. Samples were extracted with 1-120, 4% acetic acid (V/V), 10% ethanol isooctane (V/V) and olive oil separately, kept in a 70 ℃ incubator for 2 h and then filtered through a 0.2 μm microporous membrane prior to injection into an HILC-MS/ MS system. Melamine and cyanuric acid were separated, identified and quantified on HILC column by gradient mobile phase and monitored in a positive/negative electrospray ionization and multiple reaction monitor (MRM) mode. A good linear range was achieved over the concentration range of 1 -- 100 ng/mL and 2 -- 200 ng/mL for melamine and cyanuric acid in different stimulants, respectively. The limits of detection and limits of quantification were in the range of 0.4--0.8 ng/mL. The recovery rates of melamine and cyanuric acid were 134.0% --86.2% and 156.0%- 78.9% with RSDs of 6.44% -- 17.93% and 5.95%- 11.78%. This method was simple, rapid, and accurate, and suitable for the determination of melamine and cyacuric acid in food contact packaging materials.关键词
