Comparison of two different multidimensional liquid–gas chromatography interfaces for determination of mineral oil saturated hydrocarbons in foodstuffs

19-Nov-2012 | Giorgia Purcaro, Mariosimone Zoccali, Peter Quinto Tranchida, Laura Barp, Sabrina Moret, Lanfranco Conte, Paola Dugo ..., Analytical and Bioanalytical Chemistry, 2012

This investigation focused on direct comparison of two popular multidimensional liquid–gas chromatography (LC–GC) systems, the Y-interface (retention gap approach) and the syringe-based interface (programmed temperature vaporizer approach). Such transfer devices are structurally very different, ...

Exploring in vivo violacein biosynthesis by application of multivariate curve resolution on fused UV–VIS absorption, fluorescence, and liquid chromatography–mass spectrometry data

19-Nov-2012 | Clecio Dantas, Romà Tauler, Márcia Miguel Castro Ferreira, Analytical and Bioanalytical Chemistry, 2012

In this work, the application of multivariate curve resolution-alternating least squares (MCR-ALS) is proposed for extracting information from multitechnique fused multivariate data (UV–VIS absorption, fluorescence, and liquid chromatography–mass spectrometry) gathered during the biosynthesis of ...

Isotope ratio measurements with a fully simultaneous Mattauch–Herzog ICP-MS

15-Nov-2012 | Dirk Ardelt, Aleksandra Polatajko, Oliver Primm, Maurice Reijnen, Analytical and Bioanalytical Chemistry, 2012

A fully simultaneous ICP-MS, based on a compact Mattauch–Herzog geometry with a permanent magnet and a large, spatially resolving semiconductor ion detector covering the complete inorganic relevant mass range from 6Li to 238U in a single measurement, has been used to determine isotope ratios and ...

Preparation and characterization of an imprinted monolith by atom transfer radical polymerization assisted by crowding agents

15-Nov-2012 | Lu Ban, Liang Zhao, Bang-Li Deng, Yan-Ping Huang, Zhao-Sheng Liu, Analytical and Bioanalytical Chemistry, 2012

A method based on reverse atom transfer radical polymerization (R-ATRP) and molecular crowding has been used for design and synthesis of monolithic molecularly imprinted polymers (MIPs) capable of recognizing ibuprofen (IBU). 4-Vinylpyridine (4-VP) was used as the functional monomer, and ethylene ...

Gold nanorod separation and characterization by asymmetric-flow field flow fractionation with UV–Vis detection

14-Nov-2012 | Julien Gigault, Tae Joon Cho, Robert I. MacCuspie, Vincent A. Hackley, Analytical and Bioanalytical Chemistry, 2012

The application of asymmetric-flow field flow fractionation (A4F) for low aspect ratio gold nanorod (GNR) fractionation and characterization was comprehensively investigated. We report on two novel aspects of this application. The first addresses the analytical challenge involved in the ...

Effect-based proteomic detection of growth promoter abuse

14-Nov-2012 | Terence F. McGrath, Jeroen A. van Meeuwen, Anne-Cécile Massart, Edwin de Pauw, Philippe Delahaut, Jos Buijs, Aldert ..., Analytical and Bioanalytical Chemistry, 2012

Unregulated growth promoter use in food-producing animals is an issue of concern both from food safety and animal welfare perspectives. However, the monitoring of such practices is analytically challenging due to the concerted actions of users to evade detection. Techniques based on the ...

The effect of optical substrates on micro-FTIR analysis of single mammalian cells

14-Nov-2012 | Katia Wehbe, Jacob Filik, Mark D. Frogley, Gianfelice Cinque, Analytical and Bioanalytical Chemistry, 2012

The study of individual cells with infrared (IR) microspectroscopy often requires living cells to be cultured directly onto a suitable substrate. The surface effect of the specific substrates on the cell growth—viability and associated biochemistry—as well as on the IR analysis—spectral ...

Mass spectrometric techniques for characterizing low-molecular-weight resins used as paint varnishes

14-Nov-2012 | I. Bonaduce, M. P. Colombini, I. Degano, F. Di Girolamo, J. La Nasa, F. Modugno, S. Orsini, Analytical and Bioanalytical Chemistry, 2012

The molecular structure of three low-molecular-weight resins used as paint varnishes has been characterized by use of an approach based on three different mass spectrometric techniques. We investigated the ketone resin MS2A, the aldehyde resin Laropal A81, and the hydrocarbon resin Regalrez 1094, ...
