Identifying EDCs in Paper Mill Wastewaters
January 17th 2017Researchers investigating paper mill effluents and their impact on surface waters in Slovenia have identified endocrine disrupting compounds (EDCs) and their mutagenic and genotoxic properties using gas chromatography–mass spectrometry (GC–MS).
Evaluating the Potential of HPLC with IMS-MS for Metabolomics
January 1st 2017Multidimensional 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.

Phenomenex to be Acquired by Danaher Corporation
October 24th 2016Phenomenex has announced that it will be acquired by Danaher Corporation, a Fortune 150 science and technology company. Phenomenex will continue to operate as a standalone company, and will retain the Phenomenex brand, its personnel, and site locations.
Quantifying TBT Contamination in Whole Water Bodies
October 24th 2016Researchers have developed a method to quantify concentrations of the pollutant tributyltin (TBT) in whole water bodies using species-specific isotope dilution (SSID) and gas chromatography with inductively coupled plasma mass spectrometry (GC–ICP-MS).
GC–MS Analysis of Marine Organotin Pollution
October 5th 2016The ban on organotins has not led to a significant reduction in marine pollution according to research published by the Polish Academy of Sciences. Researchers found unacceptable levels of harmful organotins in the muscle and liver tissues of fish species collected in the southern Baltic Sea coastal zone, exceeding the good environmental status boundaries.
