The Reality of Lab-on-a-Chip Technology for the Mass Spectrometry Laboratory
October 1st 2009In this installment of "MS-The Practical Art," guest columnist Jack Henion presents an historical and practical overview of lab-on-a-chip (LOC) research and the commercial achievement associated with it so far.
Liquid-Liquid-Liquid Microextraction of Nerve Agents
June 1st 2009Researchers from Vertox Laboratory, Defence Research and Development Establishment (Gwalior, India) used a liquid-liquid-liquid microextraction technique followed by liquid chromatography?mass spectrometry (LC?MS) to examine alkyl alkylphosphonic acids, which are important environmental markers of nerve agents.
SPE of Lipophilic Marine Biotoxins
June 1st 2009A research group from NRL Marine Biotoxins, Federal Institute for Risk Assessment (Berlin, Germany) developed a solid-phase extraction (SPE) method for the enrichment and clean-up of lipophilic marine biotoxins from various species of bivalve molluscs and processed shellfish products.
Dispersive Liquid-Phase Microextraction of Aromatic Amines in Water
June 1st 2009Scientists from Henan Normal University (Xinxiang, China) and the University of Science and Technology Beijing (Beijing, China) developed an ultrasound-assisted ionic liquid dispersive liquid-phase microextraction procedure for determining four aromatic amines in water samples.
Analysis of Genotoxic Impurities
May 1st 2009Researchers from the Research Institute for Chromatography (Kortrijk, Belgium) and AstraZeneca R&D Charnwood (Loughborough, UK) used in-situ derivatization and liquid chromatography?mass spectrometry (LC?MS) to analyze arylamines and aminopyridines, which can be present as potentially genotoxic impurities in pharmaceutical preparations at trace levels.
Single-Drop Microextraction for Sampling Pesticides in Vegetables
April 15th 2009Researchers from the University of Thessaly (Volos, Greece) used a single-drop microextraction technique with gas chromatography (GC) and nitrogen?phosphorus and electron-capture detection to analyze pesticides in vegetables.
Headspace Sampling for Analysis of Grape Aroma Compounds
April 15th 2009Scientists from Sezione di Tecnologie Alimetari (Firenze, Italy) and the University of California, Davis (Davis, California) analyzed grape aroma compounds in Cabernet Sauvignon grapes using headspace solid-phase microextraction (SPME) with gas chromatography?mass spectrometry (GC?MS).
Dispersive Liquid-Liquid Microextraction in Antiseptic Agent Analysis
April 15th 2009Researchers from the Chinese Academy of Sciences (Beijing, China), Beijing Technology and Business University (Beijing, China), and Hebei University (Shijiazhuang, China) used dispersive liquid?liquid microextraction and ultrahigh-pressure liquid chromatography to analyze triclosan, triclocarban, and methyl-triclosan in aqueous samples.
MIP Process Used in Antiepileptic Drug Analysis
April 1st 2009Researchers from Universitat Rovira i Virgili (Tarragona, Spain) and the University of Strathclyde (Glasgow, UK) synthesized two molecularly imprinted polymers (MIPs) by precipitation polymerization using the antiepileptic drug carbamazepine as the template molecule and two types of crosslinking agents.
