Papers
Investigations of optical activity of natural products and chiral pharmaceuticals using liquid crystal technologies
Peter Raynes, Stephen J. Cowling and John W. Goodby,
Anal. Methods, 2009, 1, 88
DOI: 10.1039/b9ay00126c
Enhanced HTML article available

We demonstrate the use of novel liquid crystal technologies in the determination of enantiomeric excess and in the sensing of molecular chirality, particularly at values near to zero for menthol and ibuprofen.
A new approach for measuring the redox state and redox capacity in milk
Tomer Noyhouzer, Ron Kohen and Daniel Mandler,
Anal. Methods, 2009, 1, 93
DOI: 10.1039/b9ay00078j
Enhanced HTML article available

Milk was potentiometrically titrated using different redox mediators such as hexacyanoferrate, hexachloroiridate and iodine in order to uncover its redox capacity. Two major electroactive species were found classifying milk as a not-well poised system.
Microscale optical fibre sensor for BTEX monitoring in landfill leachate
Lurdes I. B. Silva, Alexandre V. Panteleitchouk, Ana C. Freitas, Teresa A. P. Rocha-Santos and A. C. Duarte,
Anal. Methods, 2009, 1, 100
DOI: 10.1039/b9ay00077a
Enhanced HTML article available

An optical fibre sensor has been developed for direct measurements of BTEX in landfill leachate.
A reliable mercury free chemical oxygen demand (COD) method
René Bernard Geerdink, Joyce Brouwer and Onno Jacob Epema,
Anal. Methods, 2009, 1, 108
DOI: 10.1039/b9ay00146h
Enhanced HTML article available

A simple, but reliable mercury free method to analyse chemical oxygen demand is introduced.
Interference-free determination of abscisic acid and gibberellin in plant samples using excitation-emission matrix fluorescence based on oxidation derivatization coupled with second-order calibration methods
Yuan-Na Li, Hai-Long Wu, Jin-Fang Nie, Shu-Fang Li, Yong-Jie Yu, Shu-Rong Zhang and Ru-Qin Yu,
Anal. Methods, 2009, 1, 115
DOI: 10.1039/b9ay00048h
Enhanced HTML article available

A sensitive excitation-emission fluorescence method with a second-order calibration strategy is proposed to simultaneously determine abscisic acid (ABA) and gibberellin (GA) contents in extracts of leaves and buds of ginkgo.
Phenylene-bridged hybrid silica spheres for high performance liquid chromatography
Yongping Zhang, Yu Jin, Peichun Dai, Hui Yu, Danhua Yu, Yanxiong Ke and Xinmiao Liang,
Anal. Methods, 2009, 1, 123
DOI: 10.1039/b9ay00073a
Enhanced HTML article available

Phenylene-bridged hybrid organosilicas with perfect spherical morphologies were synthesized. These materials can be used for the RP-HPLC stationary phase without further surface modification, and exhibit excellent separation performance.
Effect of salt in the mobile phase on the critical conditions of poly(ethylene glycol) in liquid chromatography-mass spectrometry coupling
Marion Girod, Emmanuel Beaudoin and Laurence Charles,
Anal. Methods, 2009, 1, 128
DOI: 10.1039/b9ay00118b
Enhanced HTML article available

Increasing the size of the cation in the mobile phase used in LCCC-ESI-MS strongly affects critical conditions of poly(ethylene glycol).
Quantitative analysis in alkaline aluminate solutions by Raman spectroscopy
W. W. Rudolph and G. T. Hefter,
Anal. Methods, 2009, 1, 132
DOI: 10.1039/b9ay00064j
Enhanced HTML article available

Fourier transform Raman spectroscopy has been used to determine industrially-relevant concentrations of aluminate, sulfate, carbonate and other anions in synthetic and plant Bayer liquors (concentrated alkaline aluminate solutions).
