Determination of 16 polycyclic aromatic hydrocarbons in milk and related products using solid-phase microextraction coupled to gas chromatography-mass spectrometry.
The proposed method was successfully applied to infant formulas, milk and related products and the presence of both fluoranthene and pyrene in two samples was confirmed. Expand
Liquid chromatography with ultraviolet absorbance detection for the analysis of tetracycline residues in honey.
The separation of tetracyclines (TCs) using reversed-phase liquid chromatography (LC) using an amide-based stationary phase prevents the interaction with the residual silanol groups and thus avoids the appearance of tailed peaks. Expand
Determination of volatile nitrosamines in meat products by microwave-assisted extraction and dispersive liquid-liquid microextraction coupled to gas chromatography-mass spectrometry.
Microwave-assisted extraction and dispersive liquid-liquid microextraction coupled with gas chromatography-mass spectrometry were evaluated, and it was concluded that sample quantification can be carried out by aqueous calibration. Expand
Dispersive liquid–liquid microextraction in food analysis. A critical review
An extensive critical evaluation of the application of dispersive liquid–liquid microextraction (DLLME) combined with chromatographic and atomic-spectroscopic methods for the determination of organicExpand
Use of headspace solid-phase microextraction coupled to liquid chromatography for the analysis of polycyclic aromatic hydrocarbons in tea infusions.
A sensitive and solvent-free procedure for the determination of 11 polycyclic aromatic hydrocarbons in tea infusions using headspace solid-phase microextraction coupled to liquid chromatography withExpand
Method development and validation for strobilurin fungicides in baby foods by solid-phase microextraction gas chromatography-mass spectrometry.
A new solvent-free method for the sensitive determination of seven strobilurin fungicides in baby food samples is described and none of the samples contained residues above the detection limits. Expand
Direct Determination of Lead, Cadmium, Zinc, and Copper in Honey by Electrothermal Atomic Absorption Spectrometry using Hydrogen Peroxide as a Matrix Modifier
Electrothermal atomic absorption spectrometric procedures for the rapid determination of copper, zinc, lead, and cadmium in honey are proposed. The samples are dissolved in a medium containing 10%Expand
Fast determination of calcium, magnesium and zinc in honey using continuous flow flame atomic absorption spectrometry.
The main advantages of the non-conventional methodology reported being automation, saving of time and a decrease in the contamination risk are reported. Expand
Comparison of two derivatization-based methods for solid-phase microextraction–gas chromatography–mass spectrometric determination of bisphenol A, bisphenol S and biphenol migrated from food cans
The method allowed the determination of the migrating levels of bisphenols found in food cans, and it was validated for linearity, detection and quantitation limits, selectivity, accuracy and precision. Expand
Determination of phenols in wines by liquid chromatography with photodiode array and fluorescence detection.
A reversed-phase LC method, optimised for the separation of trans- and cis-resveratrol, catechin, epicatechin, quercetin and rutin, is reported, although the use of a fluorimetric detector considerably lowered the detection limits. Expand
