Dichloroacetic acid (DCA) is a compound found in chlorinated drinking water. In addition, the compound is a metabolite of several halogenated solvents, including trichloroethylene (TCE) and perchloroethylene (PCE). Exposure to DCA is of... more
Following previous studies on counterfeit of wines with synthetic ingredients, the possibility of frauds by natural external L-tartaric acid has also been investigated. The aim of this research was to map the stable isotope ratios of... more
We report on the development and validation under ISO 17025 criteria of a multi-residue confirmatory method to identify and quantify 17 widely chemically different pesticides (insecticides: Carbofuran, Methiocarb, Pirimicarb, Dimethoate,... more
A method for the determination of several household biocides in water by liquid chromatography/electrospray ionisation tandem mass spectrometry (LC/ESI-MS/MS) is presented. It permits the simultaneous determination of triclosan (TCS),... more
The production of recombinant therapeutic proteins is one of the fastest growing sectors of the pharmaceutical industry, particularly monoclonal antibodies and Fc-fusion proteins. Currently, mammalian cells are the dominant production... more
The determination of the positions of double bonds after dimethyl disulfide (DMDS) addition is presented for linear or branched di-unsaturated esters and a di-substituted γ lactone. Different DMDS derivatives are studied according to the... more
ABSTRACTThis study aimed to compare Petrifilm Aerobic Count (AC) plates and the conventional pour plate methodology using the de Man–Rogosa–Sharpe (MRS) agar for the enumeration of lactic acid bacteria (LAB) in fermented milks (FMs), with... more
All four regioisomers of feruloyl quinic acid and isoferuloyl quinic acid were synthesized and a liquid chromatography/tandem mass spectrometry (LC/MS/MS) method developed that resolves all eight regioisomers. All eight regioisomers can... more
