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.
Plug & play elution into MS
The CAMAG TLC-MS Interface allows for rapid and contamination-free elution of TLC/HPTLC zones with online transfer to any given HPLC-MS system. Depending on the MS, substances can be identified within a minute. Read More
LC Troubleshooting: Be Careful of the Flow Rate
When converting methods from LC to UHPLC, don’t get confused by flow-rate settings.
 
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.
US EPA Method TO–15 – High-throughput air analysis using GC–TOF MS
This Application Note shows that the cost-effective combination of cryogen-free automation and rapid GC–TOF MS analysis delivers robust, high-throughput determination of priority hazardous air pollutants in accordance with US EPA Method TO-15. As well as allowing up to US$200,000 additional revenue to be generated per year per system, the enhanced analytical performance of the new system opens up fresh application opportunities. Read More
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.
Gingerol purification with Centrifugal Partition Chromatography SCPC-250
Gingerol, a naturally occurring plant phenol, is one of the major components of ginger. It is responsible of the characteristic taste of ginger. Centrifugal Partition Chromatography (CPC) also known as Counter Current Chromatography (CCC) is a preparative, pilot and industrial liquid purification technique that does not require traditional solid supports. CPC was used to purify few mg of gingerol from crude extract. Read More
