On-line derivatization with on-line coupled normal phase liquid chromatography–gas chromatography using the through oven transfer adsorption desorption interface: Application to the analysis of total sterols in edible oils

Autor: Ana Vázquez, Juan C. Andini, Jesús Villén, Rosa M. Toledano, Jose M. Cortés

Publikováno v: Journal of Chromatography A. 1256:191-196

In the present work on-line derivatization is combined with on-line normal phase liquid chromatography-gas chromatography (NPLC-GC) to analyze total sterols in edible oils. The method uses the TOTAD interface with an additional LC injection valve to

Analysis of polychlorinated biphenyls in transformer oils by automated online coupling reversed phase liquid chromatography-gas chromatography using the through oven transfer adsorption desorption (TOTAD) Interface

Autor: Ana Vázquez, Juan C. Andini, Rosa M. Toledano, Carlos Quintero, Jesús Villén, Jose M. Cortés

An automated method for the direct analysis of polychlorinated biphenyls (PCBs) in transformer oil is presented. The proposed method uses the TOTAD (through oven transfer adsorption desorption) interface for the on-line coupling of reversed phase liq

Large volume injection of water in gas chromatography–mass spectrometry using the Through Oven Transfer Adsorption Desorption interface: Application to multiresidue analysis of pesticides

Autor: Jesús Villén, Ana Vázquez, Juan C. Andini, Rosa M. Toledano, Jose M. Cortés

Publikováno v: Journal of chromatography. A. 1217(28)

In the present work, the potential of the Through Oven Transfer Adsorption Desorption (TOTAD) interface for the large volume injection (LVI) of aqueous samples in gas chromatography (GC) using a mass spectrometry (MS) detector is demonstrated. To thi

Automated multiresidue analysis of pesticides in olive oil by on-line reversed-phase liquid chromatography-gas chromatography using the through oven transfer adsorption-desorption interface

Autor: Ana Vázquez, Raquel Sanchez, Juan C. Andini, Jesús Villén

Publikováno v: Journal of chromatography. A. 1029(1-2)

A multiresidue, automated and rapid method for the determination of pesticide residues in olive oil is presented. The method employs the through oven transfer adsorption-desorption interface for the on-line coupling of reversed-phase liquid chromatog
