Researchers from the Lawrence Berkeley National Laboratory (Berkeley Lab) have identified the source of toxic emissions within electronic cigarettes (e-cigarettes) using headspace gas chromatography in tandem with mass spectrometry (HS-GC–MS) and high pressure liquid chromatography (HPLC).

Polymer Char are holding a “User Training Meeting” at the 6th International Conference on Polyolefin Characterization (ICPC), Shanghai, China, 6–9 November 2016.

Eurofins Lancaster Laboratories, a part of Eurofins Scientific, has announced the expansion of its Dungarvan campus. The expansion includes a new building and an expansion of existing facilities.

Water contamination has come to the forefront of global debate as a result of high profile cases such as those in Flint, Michigan, USA, or the pollution of the Ganges River in India. Koji Kosaka of the National Institute of Public Health, Japan, has investigated the contamination of the Yodo River Basin in Japan, with the precursors of the carcinogen N-Nitrosodimethylamine (NDMA). He recently spoke with The Column about his use of high performance liquid chromatography (HPLC) to uncover the source of contamination and the chemical precursors responsible.

Multidimensional liquid chromatography strategies are the most widely used method for increasing the number of spatially resolved components and reducing stress on mass spectrometric detection. However, the stress placed on a secondary dimension in a comprehensive on-line methodology is very high. An increasingly attractive approach is 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 The Column about their work evaluating this approach and exploring its possibilities for metabolomics.

The Chromatography Society is holding a four-day educational event in the Lake District from 14–17 October at the Wordsworth Hotel in Grasmere. Aimed at post-graduate students and novice chromatographers, the event will focus on the fundamentals of liquid chromatography and its practical application in industry and academia.

Leon Blumberg has been at the cutting edge of chromatography since the late 1980s. The Column spoke with him about his contribution to the past, present, and future of chromatography.

Waters Corporation has announced the addition of Richard Chang and Xiao Ran Yu to its Asia Pacific leadership team. Chang has been appointed as Vice President of Waters’ Asia Pacific Operations and Yu has been appointed as General Manager of Waters China.

LGC Standards has been awarded a Responsible Sourcing status by Sedex for its Standards division in Germany. A non-profit membership organization, Sedex is dedicated to improving responsible and ethical business practices in global supply chains.

Researchers from Colorado State University have demonstrated the viability of exploratory metabolomics and HILIC–MS in identifying biomarkers associated with dengue virus (DENV) infections, such as dengue fever, dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS).

Subcritical water chromatography (SBWC) is seen as an increasingly enticing prospect to replace high performance liquid chromatography (HPLC) in industrial settings because of its low costs and environmental impact. Yu Yang of East Carolina University, in Greenville, North Carolina, USA, has conducted research into this process for two decades. He recently spoke to Lewis Botcherby of The Column about his work, why companies should consider SBWC, and its role in pharmaceutical analysis.
