A new analytical method based on capillary zone electrophoresis-tandem mass spectrometry is proposed
and validated for the identification and simultaneous quantification of nine aminoglycosides in honey
samples. Detection using an ion trap mass analyzer operating in the multiple reaction monitoring mode
was used. Different parameters were optimized in order to obtain an adequate separation combined with
the highest sensitivity. In order to achieve high selectivity in the sample treatment, a commerciallyavailable molecularly imprinted polymer has been used for the solid phase extraction of the analytes.
Under optimum conditions, recoveries for fortified samples ranged from 88.2 to 99.8%, with relative
standard deviations lower than 8%. The limits of detection ranged from 0.4 to 28.5 mg kg 1. Furthermore,
the decision limit and the detection capability were evaluated, ranging from 3.5 to 60.5 mg kg 1 and from
6.0 to 103.1 mg kg 1, respectively, demonstrating the sensitivity and applicability of this fast and simple
method.
