LC TROUBLESHOOTING - Autosampler Carryover - This month John Dolan takes a closer look at carryover explaining what it is, how to measure it and ways of reducing it.
GC CONNECTIONS - Syringes for Gas Chromatography - John Hinshaw examines the variety of syringes on offer for gas chromatography and stresses the importance of choosing the correct syringe for a specific application.
MS IN PRACTICE - Q&A - Michael Balogh looks at the many idiosyncrasies that may hamper a mass spectrometer's performance and provides advice on where to go for help.
Simultaneous Determination of Chelating Agents by Ion-Suppression and Ion-Pair Chromatography in Wastewater - The authors compare two ion-chromatographic methods (ion suppression and ion-pair chromatography) for the simultaneous determination of four aminopolycarboxylic compounds found in nuclear waste.
2D Polymer LC as a High-Speed, High-Throughput Application - This article demonstrates how technical improvements over the last few years have led to 2D polymer liquid chromatography becoming a method that can be used for routine analysis on a daily basis.
