A method for determination of ochratoxin A (OTA) in wines using a new-solid phase extraction clean-up procedure followed with ultra performance liquid chromatography (UHPLC)-Orbitrap MS based on two scan events (full-scan Fourier transform mass spectrometer [FTMS] and higher energy-induced collision dissociation[HCD] data-dependent MS/MS) in positive ionization mode has been developed. The limit o...... hiện toàn bộ

A simple methodology for the simultaneous determination of 67 pesticides, 25 veterinary drugs, and aflatoxin M1 in raw milk was developed and validated. After evaluating different combinations of sample preparation protocols, an extraction with acetonitrile:water (2:1) with QuEChERS citrate buffer salts and a combination of RP-C18 and anhydrous magnesium sulfate for the dispersive clean-up, using ...... hiện toàn bộ
Development and Validation of Analytical Method for Clenbuterol Chiral Determination in Animal Feed by Direct Liquid ChromatographyFood Analytical Methods - Tập 8 - Trang 2647-2659 - 2015

A direct chiral liquid chromatography with UV detection method was developed and validated for enantiomeric determination of clenbuterol β2-agonist in feed samples for poultry. To obtain optimum chromatographic conditions for chiral separation, two commercially available columns packed with vancomycin and teicoplanin chiral stationary phase (150 × 2.1 mm i.d, 5 μm) were tested. Experimental design...... hiện toàn bộ
