摘要
利用超高效液相串联四级杆-飞行时间质谱联用仪建立了氯化血红素的定性、定量分析方法。采用电喷雾离子源在质谱多反应监测正离子模式下对氯化血红素进行研究。实验测得氯化血红素信号最强的特征离子对为616→557,且质量浓度在2. 5~100 mg/L具有良好的线性关系。该定量方法的检测限和定量限分别为1. 25μg/L和4. 00μg/L,回收率80. 65%~102. 99%,精密度为3. 84%。该方法能有效用于保健品中氯化血红素的定性、定量分析。
A rapid and sensitive qualitative and quantitative analysis method for hemin by ultra-high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry( UHPLC-QTOF-MS) was established. The electrospray ion source was used for studying hemin at mass spectrometry multiple reaction monitoring positive ion mode. The characteristic ion pair with the strongest hemin signal was 616→557,and there was a good linear relationship in the range of 2. 5-100 mg/L. The detection and quantitation limits of the method were 1. 25 μg/L and 4. 0μg/L,respectively. The recovery rate ranged from 80. 65% to 102. 99%,and the precision was 3. 84%. The results show that the method has high recovery rate and good precision,and therefore can be effectively used for quantitative and qualitative analysis of hemin in health care products.
