Detecting Carcinogens in Drinking Water
Water contamination has come to the forefront of global debate as a result of high profile cases such as those in Flint, Michigan, or the pollution of the Ganges River in India. Koji Kosaka of the National Institute of Public Health, Japan, has investigated the contamination of the Yodo River Basin in Japan, with the precursors of the carcinogen N-Nitrosodimethylamine (NDMA). He recently spoke to LCGC about his use of high performance liquid chromatography (HPLC) to uncover the source of contamination and the chemical precursors responsible.
Analysis of Cations in drinking water, environmental water and wastewater
Cations are routinely monitored for regulatory compliance and hardness. Ammonia produced from treatment plants poses a severe threat to aquatic life. Monitoring of ammonium is required in the US, EU and Japan in both wastewater and drinking water. Ethanolamines, used as additives in power plant waters, are also an environmental concern. Learn more

LC–MS and GC–MS Analysis of Honeybee Pesticides
Liquid chromatography coupled to tandem mass spectrometry (LC–MS–MS) alongside gas chromatography tandem mass spectrometry (GC–MS–MS) has been used to analyze 200 pesticides and pesticide metabolites in honeybees.
 
Application Note
Ion chromatography (IC) in a single run can determine ammonium plus all the important inorganic cations, including lithium, sodium, potassium, magnesium, and calcium. This Note discusses the linear range, method detection limits, and analyte recoveries obtained with the Dionex IonPac CS16 column, and evaluates the effect of potential interferences on method performance during the analysis of typical environmental samples.

Advancing Ion Chromatography with High Pressure
High pressures and columns with small particle sizes have been used in high-performance liquid chromatography (HPLC) for a long time, but not in ion chromatography (IC). But now, high pressures are coming to IC. Read this new e-book to learn more.

Advancing GC Methods and Environmental Analysis
Gas chromatography (GC) is a powerful technique for environmental analysis. The articles in this new e-book look at both the technique and its application, providing essential information about GC fundamentals as well as an example of how the technique can be used in new ways in environmental analysis.
