Researchers 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).

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.

Research on nasal spray formulation has yielded an improved in vitro analytical test method utilizing thin layer chromatography (TLC). The research used simulated nasal mucus with varying properties and a TLC apparatus to assess the dripping behaviour of nasal formulations to improve the nasal spray development process.Nasal Spray Evaluation Using Thin Layer Chromatography

Rudolf Krska of the University of Natural Resources and Life Sciences (BOKU), in Vienna, Austria, has been awarded the biennial B.R.A.I.N award at the Biomin scientific conference held in Vancouver, Canada.

Professor James Jorgenson of the University of North Carolina at Chapel Hill, in North Carolina, USA, has received the Csaba Horváth Medal and Scroll at the Csaba Horváth Memorial Award Symposium, Yale West Campus Conference Center.

Agilent Technologies Inc. has named Roeland G.W. Verhaak, of the Jackson Laboratory (JAX), the winner of the company’s Early Career Professor Award. Verhaak was selected for his contributions to the implementation of transcriptomics, genomics, and big-data analysis to the classification and diagnosis of various cancer types.

Researchers from Postnova Analytics, Landsberg, Germany, have developed a quantitative method to detect traces of toxic metals in tattoo ink using asymmetrical flow field-flow fractionation in combination with inductively coupled plasma mass spectrometry (AF4-ICP-MS).

Phenomenex 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.

Researchers 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).

The Waters’ scientists responsible for the development of the QTOF mass spectrometer have been honoured at the annual Human Proteome Organization.

The 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.

LFMC.jpg

Biopharmaceutical purification techniques can be slow and cumbersome with poor scalability. A new device using laterally-fed membrane chromatography (LFMC) was developed to address these issues. Raja Ghosh from McMaster University in Hamilton, Ontario, Canada, spoke to The Column about this new device and its potential applications.

Biotage AB has announced the purchase of shares in the Danish biomolecule company Chreto Aps, representing a significant investment into the area of drug development.

CASSS Backdrop.jpg

What are the motivations and events that drive a successful separation scientist? This is the question that CASSS seeks to answer by documenting the lives and careers of the analytical chemists who have won their “Outstanding Achievements in Separation Science” Award.
