Here are the top five articles that the editors of LCGC International published this week.
Environmental Forensics in the Workplace
November 5th 2015Populations worldwide are exposed to polychlorinated biphenyls (PCBs) that can be harmful to human health. The Column spoke to David Megson from Ryerson University in Toronto, Canada, about recent developments in assessing human exposure to PCBs and chiral enantiomer fractions (EFs) in the workplace.
MS Detection of Waste in Public Swimming Facilities
October 3rd 2015Is your swimming pool clean and safe? Recreational water illness, most commonly in the form of digestive tract illness or skin, ear, or respiratory infections, is often caused by water contamination. The authors present a robust method, using solid-phase extraction and high-resolution mass spectrometry, for monitoring swimming pool water.
New Developments in the Analysis of Complex Environmental Matrices
October 24th 2014The RSC Environmental Chemistry Group and the RSC Analytical Division Separation Science Group will hold a joint meeting entitled "New Developments in the Analysis of Complex Environmental Matrices" in London, UK, on 6 February 2015.
Applying Gas Chromatography to Environmental Geochemistry
October 6th 2014In the second of a two-part Q&A, The Column spoke to Paul A. Sutton, a research fellow in the Petroleum and Environmental Geochemistry Group at Plymouth University (Plymouth, UK), about his experience with high temperature gas chromatography (HTGC), and his best practices for analysts in the lab.
Applying Gas Chromatography to Environmental Geochemistry
July 24th 2014In the first of a two-part Q&A The Column spoke to Paul A. Sutton, a research fellow in the Petroleum and Environmental Geochemistry Group (PEGG) at Plymouth University (Plymouth, UK), about the analysis of crude oil and how high temperature gas chromatography can be used to save millions of dollars for the oil industry.
Striking Oil: Separation Science in Marine Pollution Analysis
December 17th 2013Chris Reddy from the Woods Hole Oceanographic Institution spoke to LCGC about the role of chromatography in the ongoing environmental analysis of the Deepwater Horizon oil spill, how comprehensive GCXGC works in practice, and why this oil spill led to the return of thin layer chromatography (TLC) to his laboratory.
Using HPLC-MS-MS to Detect Pharmaceutical Contaminants in Water
September 18th 2013LCGC recently spoke with Edward T. Furlong of the Methods Research and Development Program at the National Water Quality Laboratory with the U.S. Geological Survey (USGS) about his group's work on developing new methods to detect pharmaceutical contaminants in waterways.
IC-MS and IC-ICP-MS in Environmental Research
November 21st 2012Since its introduction in 1975, ion chromatography (IC) has been used in most areas of analytical chemistry and has become a versatile and powerful technique for the analysis of a vast number of ions present in the environment. This article is a review of possible uses of IC in combination with MS detection for environmental research.
Fast Online SPE Purification of Stevia Plant Extracts
September 6th 2012Sample clean-up using solid-phase extraction (SPE) and similar methods can sometimes be both time-consuming and expensive. The purification of complex plant extracts requires special care in particular. A robust and sensitive online SPE sample preparation method is described for the determination of steviol glycosides.
Screening of Pollutants in Water Samples and Extracts from Passive Samplers using LC–MS and GC–MS
August 1st 2012This article describes the GC–MS and LC–MS screening methods developed by the Environment Agency for England and Wales for the analysis of both low-volumn water samples and extracts obtained from various designs of passive samplers.
Suffering from Sick Building Syndrome
April 2nd 2012Building products used indoors in homes and offices can have a significant impact on indoor air quality (IAQ) through the emission of volatile- or semi-volatile organic compounds (VOCs/SVOCs). In order to protect the health and well-being of occupants in homes and company buildings from potentially toxic emissions, EU and national regulations require that products used indoors be tested following clearly defined methods.
