Development and validation of a liquid chromatography isotope dilution mass spectrometry method for the reliable quantificationof alkylphenols in environmental water samples by isotopepattern deconvolution
Fabregat-Cabello, Neus; Sancho, Juan V; Vidal-Albalat, Andreu; González, Florenci; Roig-Navarro, Antoni F. Copyright © 2015 Elsevier (2014-02-07)We present here a new measurement method for the rapid extraction and accurate quantification of technical nonylphenol (NP) and 4-t-octylphenol (OP) in complex matrix water samples by UHPLC-ESI-MS/MS. The extraction of ... -
Fast methodology for the reliable determination of nonylphenol in water samples by minimal labeling isotope dilution mass spectrometry
Fabregat-Cabello, Neus; Castillo Tirado, Ángel; Sancho, Juan V; González, Florenci; Roig-Navarro, Antoni F. Elsevier (2013-08)In this work we have developed and validated an accurate and fast methodology for the determination of 4-nonylphenol (technical mixture) in complex matrix water samples by UHPLC–ESI-MS/MS. The procedure is based on isotope ... -
Method development and validation for the determination of selected endocrine disrupting compounds by liquid chromatography mass spectrometry and isotope pattern deconvolution in water samples. Comparison of two extraction techniques
Fabregat-Cabello, Neus; Pitarch-Motellón, Jorge; Sancho, Juan V; Ibáñez, Maria; Roig-Navarro, Antoni F. Royal Society of Chemistry (2016)In the present work two different extraction methodologies have been developed and validated for the determination of t-octylphenol and a technical mixture of nonylphenol (both, priority substances of EU water policy) and ...
