Determination of Ocratoxin A by capillary HPLC with laser induced fluorescence detection

Posted on 6 July, 2010 by fqm302

In this abstract we propose the coupling of capillary-HPLC with LIF for the analysis of OTA, using anionic micellar medium in the mobile phase, which constitutes a very efficient alternative, increasing sensitivity and selectivity. To the best of our knowledge, … Continue reading →

On-line preconcentration for the determination of aflatoxins in rice samples by micellar electrokinetic capillary chromatography with laser induced fluorescence detection

Posted on 30 June, 2010 by fqm302

MEKC coupling with LIF detection has been used for the determination of four aflatoxins (B1, B2, G1 and G2). Separations were performed in an uncoated fused-silica capillary (70 cm×75 μm id, 55 cm effective length), using 20 mM borate buffer with 30 mM SDS (pH … Continue reading →
