Multi-residue pesticide analysis in virgin olive oil by nanoflow liquid chromatography high resolution mass spectrometry
(Elsevier Science, 2018-08)
In this article, a nanoflow liquid chromatography system coupled to high resolution mass spectrometry (nanoflow LC/ESI Q-Orbitrap-MS) has been applied for the development of a multiresidue pesticide method for the determination ...
Determination of five pesticides in juice, fruit and vegetable samples by means of liquid chromatography combined with multivariate curve resolution
(Elsevier Science, 2014-02)
The aim of this work was to quantify five commonly used pesticides (propoxur, carbaryl, carbendazim, thiabendazole and fuberidazole) in real samples as: tomato, orange juice, grapefruit juice, lemon and tangerine. The ...
Multivariate calibration-assisted high-performance liquid chromatography with dual UV and fluorimetric detection for the analysis of natural and synthetic sex hormones in environmental waters and sediments
(Elsevier, 2016-02)
A green method is reported based on non-sophisticated instrumental for the quantification of seven natural and synthetic estrogens, three progestagens and one androgen in the presence of real interferences. The method takes ...
Determination of estrogens and their catechol metabolites by ultra- high-performance liquid chromatography?time-of-flight high- resolution mass spectrometry
(2017)
An ultra-high-performance liquid chromatography separation was coupled to a dual ESI
source with time-of-flight high-resolution mass spectrometry (UHPLC-ESI-TOF/MS) for the
determination of steroidal hormones. Hormones ...
Simultaneous multi-residue determination of twenty one veterinary drugs in poultry litter by modeling three-way liquid chromatography with fluorescence and absorption detection data
(Elsevier Science, 2017-02)
A method for the simultaneous investigation of twenty one veterinary active ingredients in poultry litter basedon MCR-ALS modeling of three-way liquid chromatography with fluorescence and UV detection data ispresented. The ...
