Electronically Controlling Carrier Gas Pressure, Flow, and Velocity
October 1st 2014Have you wondered how your GC system sets and controls gas pressures, flows, and carrier gas velocities electronically? Here, we describe the requirements for and the operation of electronic gas control systems for GC columns and detectors.
Quantifying Proteins by Mass Spectrometry
October 1st 2014The quantification of proteins in a complex biological sample is an important and challenging task. Mass spectrometry (MS) is increasingly used for this purpose, not only to give a global survey of the components and their amounts, but also to precisely and accurately quantify specific target proteins.
Unraveling the Links Between Diet and Human Health Using LC–MS-MS
October 1st 2014We recently spoke to Gary Duncan and Wendy Russell of the Rowett Institute of Nutrition & Health in Aberdeen, Scotland, about the significance of phytochemical bioavailability to human health and the important role of liquid chromatography linked to tandem mass spectrometry (LC–MS-MS) in their research.
Waters Opens Global Mass Spectrometry HQ in UK
September 25th 2014Waters Corporation (Massachusetts, USA) has opened a new custom-built mass spectrometry headquarters in Wilmslow, UK. The new headquarters took less than two years to construct from the initial ground breaking to completion, and brings together existing centres in the region consisting of more than 500 employees.

Analysis of Breast Milk to Determine Agent Orange Exposure
September 24th 2014Scientists in Vietnam have performed high?resolution gas chromatography coupled with high-resolution mass spectrometry (HRGC?HRMS) analysis of breast milk to determine the level of dioxin and furan exposure around the Da Nang Agent Orange hotspot in Vietnam.1 Agent Orange contamination is associated with elevated and persistent levels of dioxins and furans in the environment and are associated with the occurrence of birth defects among other side effects.
World of Technology & Science (WOTS) 2014
September 19th 2014The World of Technology & Science 2014 (WOTS) exhibition will be held between 30 September and 3 October 2014 at the Jaarbeurs Exhibition and Conference Centre, Utrecht, The Netherlands, organized by two collaborating Dutch associations, FHI (Federation of Technology Branches) and FEDA.
Optimizing Flavour Analysis Using Modern Heart-Cutting MDGC
September 19th 2014This review discusses recent technological advances in classical heart-cuttting two-dimensional gas chromatography (GC–GC). These developments are then illustrated by application to analysis of important flavour compounds at trace levels in very complex matrices
