Featured Article Sealing it with Septa While gas chromatographers may take their septa for granted, in fact these small and seemingly unremarkable polymer disks keep air out of the carrier-gas stream when used in an inlet and keep samples intact and uncontaminated when used in sample vials. Choosing the wrong septa can compromise method accuracy and repeatability as well as reduce column life in extreme cases. This instalment of "GC Connections" addresses septa for inlets and sample vials. /Read more/ advertisment New Agilent 1260 Infinity II LC Put your trust in the LC platform that runs, and runs, and runs.

Learn more LCGC TV Customizing SPME Coatings for Individual Analytes Most SPME sorbent coatings are broadly selective. Jared Anderson from the Iowa State University discusses why there is a need to design coatings for SPME analysis that are more targeted for specific types of analytes and the rewards that can be reaped. /Read more/ advertisment Mass Spectral Studies of Polypropylene Chromatographic Well Plates Improve productivity, while minimizing errors with Thermo Scientific™ WebSeal™, a comprehensive range of polypropylene well plates and seals for analytical challenges and various chromatographic applications.

Featured Article Evaluating the Potential of HPLC with IMS-MS for Metabolomics The coupling of high performance liquid chromatography (HPLC) with ion mobility spectrometry hyphenated to mass spectrometry (IMS-MS). Tim Causon and Stephan Hann of the University of Natural Resources and Life Sciences in Vienna, Austria, spoke to LCGC about their work evaluating this approach and exploring its possibilities for metabolomics. /Read more/ The LCGC Blog Top-Down Protein Quantitation on a Triple-Quadrupole Mass Spectrometer Top-down protein quantitation, especially using triple-quadrupole MS, but even in general, has hardly been pursued. To help fill this gap, we recently reported a systematic investigation of intact-protein quantitation using multiple reaction monitoring (MRM) on a triple-quadrupole MS system, and we believe that this approach can be a promising alternative route to consider going forward. /Read more/ advertisment The 31st International Symposium on Chromatography The 31st International Symposium on Chromatography will bring together experts interested in the contribution of Chromatography & Separation science to meet the needs of the pharmaceutical industry, food, health, and medicine. The conference runs over 3 days from August 28th-Sep 1st, 2016. 800 delegates will attend ISC in University College Cork, one of Ireland's most prestigious venues.
