Capabilities of microbore columns coupled to inductively coupled plasma mass spectrometry in speciation of arsenic and selenium
Castillo Tirado, Ángel; Roig-Navarro, Antoni F.; Pozo, Óscar J. Elsevier (2008)The performance of microHPLC-microconcentric nebulizer-inductively coupled plasma-mass spectrometry (ICP-MS) coupling for the simultaneous determination of As(III), As(V), monomethylarsenic acid (MMA), dimethylarsinic acid ... -
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 ... -
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 ... -
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. ... -
Rapid screening of arsenic species in urine from exposed human by inductively coupled plasma mass spectrometry with germanium as internal standard
Castillo Tirado, Ángel; Fabregat-Cabello, Neus; Roig-Navarro, Antoni F.; Boix Sales, Clara; Rodríguez-Castrillón, J.A. Royal Society of Chemistry (2012)In the present work, internal standardization based on species-unspecific isotope dilution analysis technique is proposed in order to overcome the matrix effects and signal drift originated in the speciation of As in urine ...
