LC TROUBLESHOOTING
Listen to the Data
John Dolan describes a stepwise process to help isolate and identify the cause of a method failure.

GC CONNECTIONS
Gas Chromatography Ovens
The transit of peaks through a gas chromatography (GC) column depends strongly on the thermal profile they encounter on the way. Gas chromatographers primarily rely on the classic hot air bath type of oven, but several alternatives are also in use. This instalment from John Hinshaw examines ovens for GC in several forms plus how oven thermals affect peak retention behaviour.

HPLC Stationary Phase Selection
A guide to selecting the correct HPLC stationary phase for your method.

PEER-REVIEWED ARTICLES
Advances in Electrochemistry
Redox reactions are integral parts of many cellular processes. They are therefore extensively studied in vitro and in vivo. Electrochemistry represents a purely instrumental approach to characterize direct and indirect effects of redox reactions on bioorganic molecules. This review highlights important trends and recent development in electrochemistry.

Environmental Analysis of cPACs Using Chiral LC–MS
This article gives an up-to-date commentary on chiral liquid chromatography coupled with mass spectrometry for the determination of pharmacologically active chiral compounds (cPACs) (including illicit drugs) in environmental matrices. Several applications are discussed to demonstrate the benefits of performing environmental analysis of cPACs at the enantiomeric level. Finally, future perspectives in this rapidly developing field of research are outlined.
