An anionic micellar medium was added to the  mobile phase for increasing the fluorescence intensity and peak  efficiency. Dispersive liquid\u2013liquid microextraction (DLLME) has been  used as a simple and efficient sample pretreatment method for the  analysis of OTA in wines, being optimised by means of experimental  design. The limit of detection was 5.5\u00a0ng\u00a0L<sup>\u22121<\/sup> (3\u00a0\u00d7\u00a0S\/N) and  recoveries for different wines ranged from 91.7 to 98.1%. The proposed  methodology could be classified as a green analytical chemistry  alternative, combining the low organic solvent volumes required in the  DLLME with the reduced consumption of mobile phase in capillary HPLC.  The use of LIF as detector provided an extremely sensitive method for  the determination of OTA in wines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A method based on reverse phase capillary high performance liquid chromatography (capillary HPLC) coupled to laser-induced fluorescence detection (LIF) has been proposed for the determination of ochratoxin A (OTA) in wine samples.
