Evaluation of uncertainty sources in the determination of testosterone in urine by calibration-based and isotope dilution quantification using ultra high performance liquid chromatography tandem mass spectrometry
Pitarch-Motellón, Jorge; Roig-Navarro, Antoni F.; Sancho, Juan V; Ibáñez, Maria; Fabregat-Cabello, Neus; Pozo, Óscar J.; Ventura, Rosa; García Alonso, J. Ignacio; Rodríguez González, Pablo; González Gago, Adriana; Ereño Artabe, Amaia; Van Eenoo, Peter; Deventer, Koen; Dehnes, Yvette; Rzeppa, Sebastian Elsevier (2017-06)Three quantification methodologies, namely calibration with internal standard (Cal-IS, non-weighted), weighted calibration with internal standard (wCal-IS) and isotope pattern deconvolution (IPD) have been used for the ... -
Fast and Accurate Procedure for the Determination of Cr(VI) in Solid Samples by Isotope Dilution Mass Spectrometry
Fabregat-Cabello, Neus; Rodríguez González, Pablo; Castillo Tirado, Ángel; Malherbe, Julien; Roig-Navarro, Antoni F.; Long, Stephen E.; García Alonso, J. Ignacio American Chemical Society (2012)We present here a new environmental measurement method for the rapid extraction and accurate quantification of Cr(VI) in solid samples. The quantitative extraction of Cr(VI) is achieved in 10 minutes by means of focused ... -
Isotope Dilution LC-ESI-MS/MS and low resolution Selected Reaction Monitoring as a tool for the accurate quantification of urinary testosterone
Ereño Artabe, Amaia; Gonzalez-Gago, Adriana; Suarez Fernández, Amanda; Pitarch-Motellón, Jorge; Roig-Navarro, Antoni F.; Pozo, Óscar J.; Rodríguez González, Pablo; García Alonso, J. Ignacio Elsevier (2018-09)A new analytical method for the quantification of testosterone in human urine samples by isotope dilution mass spectrometry is proposed. A standard solution of 13C2-testosterone is added to the samples at the beginning of ... -
Isotope pattern deconvolution-tandem mass spectrometry for the determination and confirmation of diclofenac in wastewaters
Castillo Tirado, Ángel; GRACIA LOR, EMMA; Roig-Navarro, Antoni F.; Sancho, Juan V; Rodríguez González, Pablo; García Alonso, J. Ignacio Elsevier (2013-02-26)Isotope dilution mass spectrometry (IDMS) based on isotope pattern deconvolution (IPD) has been applied here to MS/MS (QqQ) in order to carry out the quantification and confirmation of organic compounds in complex matrix ... -
Multiple Spiking Species-Specific Isotope Dilution Analysis by Molecular Mass Spectrometry: Simultaneous Determination of Inorganic Mercury and Methylmercury in Fish Tissues
Castillo Tirado, Ángel; Rodríguez González, Pablo; Centineo, Giuseppe; Roig-Navarro, Antoni F.; García Alonso, J. Ignacio American Chemical Society (2010)This work demonstrates, for the first time, the applicability of multiple spiking isotope dilution analysis to molecular mass spectrometry exemplified by the speciation analysis of mercury using GC(EI)MS instrumentation. ...
