Ultrasound-assisted surfactant-enhanced emulsification microextraction for the determination of carbamates in wines by ultra-high performance liquid chromatography–tandem mass spectrometry

Posted on 14 October, 2013 by fqm302

A new sensitive multiresidue method based on ultra-high performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) has been developed for the detection, confirmation and quantification of twenty five carbamates in wine samples. The separation was achieved in 5.5 min, using a Zorbax Eclipse … Continue reading →

Comparison of different sample treatments for the analysis of ochratoxin A in wine by capillary HPLC with laser-induced fluorescence detection

Posted on 2 November, 2011 by fqm302

Ochratoxin A (OTA) is a mycotoxin naturally found in various foods, including wine. As OTA is considered as a possible human carcinogen, the maximum concentration for this compound has been established at 2 μg kg−1 in wine by the EU (Directive (CE) … Continue reading →
