Multi-residue method for the analysis of commonly used commercial surfactants, homologues and ethoxymers, in marine sediments by liquid chromatography-electrospray mass spectrometry

Autor: F.J. Camino-Sánchez, José Luis Vilchez, Alberto Zafra-Gómez, B. Oliver-Rodríguez, J.P. Pérez-Trujillo, J.E. Conde-González

Publikováno v: Microchemical Journal. 110:158-168

A simple, sensitive and accurate multi-residue method has been developed for simultaneous determination of the main types of surfactants (linear alkylbenzene sulfonates [LAS], alkyl sulfates [AS], alkyl ethoxysulfates [AES], and alcohol polyethoxylat

Validation of a GC–MS/MS method for simultaneous determination of 86 persistent organic pollutants in marine sediments by pressurized liquid extraction followed by stir bar sorptive extraction

Autor: José C. Marques, Alberto Zafra-Gómez, F.J. Camino-Sánchez, J.E. Conde-González, J.P. Pérez-Trujillo, José Luis Vilchez

Publikováno v: Chemosphere. 84:869-881

A multiresidue method for the analysis of 86 persistent pollutants in marine sediments at ultra-trace level has been developed and validated using pressurized liquid extraction (PLE) and stir-bar sorptive extraction (SBSE) coupled with thermal desorp

Chemical characterization of bottled sweet wines from the Canary Islands (Spain)

Autor: J.P. Pérez-Trujillo, Eugenio Díaz Díaz, C. Díaz Romero, S. Tort

Publikováno v: Acta Alimentaria. 32:247-256

Samples of sweet wines from the Canary Islands belonging to the Denominations of Origin of La Palma and Lanzarote islands were analysed in relation to chemical parameters. The main chemical parameters analysed demonstrated that these wines fulfil all

Chemometric Study of Bottled Wines with Denomination of Origin from the Canary Islands (Spain) Based on Ultra-Trace Elemental Content Determined by ICP-MS

Autor: J.P Pérez-Trujillo, Mireille Barbaste, Bernard Medina

Publikováno v: Analytical Letters. 36:679-697

This study determined the content in 39 trace and ultratrace elements, among them 16 rare earth elements, in 153 wines from the Canary Islands (Spain). Analyses were performed by ICP-MS. Rare earth elements were strongly correlated among one another,

Contents of Trace and Ultratrace Elements in Wines from the Canary Islands (Spain) as Determined by ICP-MS

Autor: J.P Pérez-Trujillo, Bernard Medina, Mireille Barbaste

Publikováno v: Journal of Wine Research. 13:243-256

One hundred and fifty-three white, rose and red wine samples from the Canary Islands (Spain) were analysed. The wines were sampled from two different vintages, eight denominations of origin, and four islands. The concentration of 20 trace and ultratr
