This month's "LC Troubleshooting" instalment looks at two reader-submitted questions regarding method calibration.

Microwave-accelerated extraction (MAE) is described and evaluated. The latest enhancements to this technology are discussed from a hardware and applications perspective.

The session chair for this Wednesday afternoon session is Chao Yan of Shanghai Jiao Tong University (China). The session will be held in room HEC-C in the Hilton Exhibition Center on the second floor of the Hilton, beginning at 1:30 p.m.

Emily Hilder of the University of Tasmania (Australia) - and LCGC Editorial Advisory Board member - will chair this Monday morning session in room HEC-A, Hilton Exhibition Center (second floor of the Hilton). The session will begin at 9:00 a.m.

This Wednesday afternoon session will cover several interesting ways that LC?MS techniques are applied to biological applications. This session will begin at 1:30 p.m. and conclude at 3:00 p.m. Sarah Trimpin of Wayne State University in Detroit, Michigan will chair the session.

This Tuesday morning session will cover some new advances in ultra-high pressure liquid chromatography (UHPLC). The session will start at 8:30 a.m. and conclude around 10:00 a.m. The session will be chaired by Monika Dittmann of Agilent Technologies in Germany.

This Tuesday afternoon session will be chaired by Martin Gilar of Waters Corporation (Milford, Massachusetts) and will be held in room HEC-A of the Hilton Exhibition Center on the second floor of the Hilton. The symposium will begin at 1:30 p.m. with the presentation of the Uwe Neue Award.

In this study, the quality-by-design principle is applied instead of trial-and-error in the development of a liquid chromatography (LC) method. A mixture of an active pharmaceutical ingredient and its 13 impurities was analyzed on a short narrow-bore column (50 mm ? 2.1 mm, packed with sub-2-?m particles) providing short analysis times. The performance of commercial modelling software for robustness testing was systematically compared to experimental measurements and design-of-experiment–based predictions.

This study presents results of gel permeation chromatography (GPC) and analytical temperature rising elution fractionation (TREF) of polyethylene in butylal (dibutoxymethane, a halogen-free solvent).

A multi-residue method has been developed and validated for the analysis of methylxanthines (caffeine and its metabolites) and cotinine in human plasma. The method has been successfully applied to the analysis of 500 samples from pregnant women in a clinical study.

The power of MS-MS analysis applied to GC analysis, including the instrumentation, experiment types, and application areas

A team of scientists in Portugal and Spain have performed high performance liquid chromatography coupled with fluorescence detection (HPLC– FLD) to show that marinating pork meat in beer can reduce the levels of polycyclic aromatic hydrocarbons (PAHs) formed when grilled over charcoal.
