摘要：

Liquid chromatography coupled to mass spectrometry (LC-MS), especially by the use of electrospray ionisation source (ESI), is currently used for the analysis of heterocyclic aromatic amines (HAs) in complex samples. The present paper describes the study of the performance of different narrow-bore reversed-phase columns to achieve the best chromatographic separation for the determination of 16 HAs by LC-ESI-MS in food samples. Different parameters such as peak symmetry, resolution and number of theoretical plates have been evaluated for each column, using different chromatographic conditions. The column that provided the best results was TSK Gel(R) Semi-Micro ODS-80TS of Tosohaas. Quality parameters have been established, obtaining good short-term precision in all cases (relative standard deviation (R.S.D.) lower than 7.7%) and low limits of detection (< 13 pg injected in MS and < 16 pg injected in MS/MS). The content of HAs in two beef extracts have been determined. (C) 2003 Elsevier B.V. All rights reserved.
