An overview of some recently developed mass spectrometry techniques and their applications to marine biotoxins.

The author describes the development of a method for the extraction, clean-up, and successful analysis of polybrominated diphenyl ethers (PBDEs) in fish tissue, soil, and water.

In the first instalment of this new column, Massart and Vander Heyden review the subject of chemometrics, and in particular its relevance to separation science. The column aims to explain how application of chemometrical techniques can improve both the design of robust analytical methods and the subsequent interpretation of derived results.

The authors look at how achieving both greater throughput and increasing informational content is a driving force in small-molecule analysis. They describe how analysts should address mechanical increases in productivity, software implementation flow and data management, and effective sample preparation to improve efficiency and reduce frustration.

This month's LC?GC Europe features the first instalment of a brand-new column. Following many requests from readers, "Practical Data Handling" will concentrate on chemometrics.

Dolan addresses the problems associated with transfering a validated method from one laboratory to another and considers what changes are permissable.

The use of SLM extraction in speciation studies is discussed, especially for determining the form and bioavailable fractions of metals in enviromental and biological matrices.

MIPs are synthetic polymeric materials possessing specific cavities designed for a target molecule. The various parameters affecting extraction selectivity are discussed in the article and the potential of MIPs as selective sorbents reviewed.

The authors discuss zero-, first- and second-order data and describe the advantages of using second-order chromatographic data compared with the more traditional univariate or multivariate calibration. They demonstrate how its use can uncover much more information from chromatograms and spectra.

The authors consider the impact an analytical balance can have on the quality of chromatographic analyses.

A look back at the life of this chromatography pioneer.
