Separating and Identifying Trace-Level Chemicals in Wine by Headspace SPME with GC×GC–TOF MS
May 6th 2015Solid-phase microextraction (SPME) coupled with comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry (GC×GC–TOF-MS) can be used to detect trace-level fungicides and compounds responsible for undesirable attributes known as “organoleptic faults” in wine. Of particular interest is the analysis of trace-level fungicides, which are difficult to detect using conventional quadrupole GC–MS techniques without resorting to selected ion monitoring mode.
Novel Strategies for Biopharmaceutical Purification
May 6th 2015The biopharmaceutical industry continues to expand in response to a demand for novel biopharmaceuticals. José Paulo Mota from the Faculty of Science and Engineering (FCT-UNL) of Universidade Nova de Lisboa and the Institute of Experimental and Technological Biology (IBET), Portugal, has been working on the development of chromatographic techniques to speed up the purification of biopharmaceuticals, specifically adenoviruses. Bethany Degg of The Column spoke to him about his work.
Markes International Wins Queen’s Award for Enterprise
May 6th 2015Markes International (Llantrisant, UK) has been awarded a 2015 Queen’s Award for Enterprise in International Trade decreed by Her Majesty The Queen of Great Britain, on the recommendation of the Prime Minister, David Cameron. The awards are announced each year on the Queen’s birthday, 21 April.
Analyzing Shipwrecked Beer from 1840s Using GC–MS
May 6th 2015Beer 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.
Agilent Technologies and Scion Announce GC Instrument Control Agreement
May 6th 2015Agilent Technologies (California, USA) and Scion Instruments (California, USA) have announced a gas chromatography instrument agreement, which will allow users to operate instruments from both manufacturers in each company’s chromatography data systems.
Investigating the Link Between PBDE Exposure and Feline Hyperthyroidism
May 6th 2015Exposure to flame retardant additives could be a contributing factor to the occurrence of feline hyperthyroidism (FH) in Swedish cats, according to a new study. The authors also suggest that pet cats can be studied as markers of environmental contamination in the home.
