Torsten C. Schmidt from the University Duisburg-Essen in Germany recently developed an in-tube extraction (ITEX) method for headspace sampling of beer prior to gas chromatography–mass spectrometry (GC–MS). In this video he discusses the principles of the technique and its advantages over other methods.

Helium to Hydrogen — Would a Change Do You Good?
Change is always a scary concept. To help with this, John Hinshaw addresses common questions associated with changing from helium to hydrogen gas.
Micro-SPE Desalting With Reduced Losses
New! Micro-volume TARGA® C18 SPE chemistries to desalt peptide, glycopeptide or glycan samples. Desalting with the water wettable, TARGA® C18 UltraMicroSpin™ columns, by loading in 100% water, improves recovery of these polar molecules prior to LCMS. Try our TARGA C18 as your desalting protocol, today! The Nest Group, Inc. - "Not Just Columns ... Answers!"
The LCGC Blog: Troubleshooting Retention Time Issues in Gradient HPLC
While some of the relationships between parameters in gradient HPLC are complex, others are reasonably straightforward. Here, Tony Taylor explains, through an example, how adjusting the flow rate can improve resolution between critical peak pairs.

Beer from a 1840s shipwreck in the Baltic Sea has been analyzed by a team of scientists at the VTT Technical Research Centre in Finland. Using a variety of chromatography techniques — including gas chromatography coupled to mass spectrometry (GC–MS) and high-performance anion-exchange chromatography (HPAEC) coupled to MS — the team compared the beer with modern-day varieties and found they were not too dissimilar.
