So, the time has come to replace that aging instrument sitting in the corner of your lab; the problem is, with only a handful of real market leaders and dozens of cheaper off-shore instruments, how do you select the instrument that best suits your needs?

Development of a Method to Better Quantify Levels of the Persistent Organic Pollutants Iodinated X-Ray Contrast Media and Artificial Sweeteners Found in Water

by Waldemar Ens, Frank Senner, Benjamin Gygax, Götz Schlotterbeck, Genevac

Abstract: Persistent organic pollutants (POPs) can cause long term damage to the environment. Two classes of organic molecules have come to the attention of regulators and water treatment authorities in recent years; iodinated X-Ray contrast media (XCM) and artificial sweeteners (AS). These molecules, by design, have a high degree of stability. Aware of the increased abundance of these molecules in waste water, the IWB Water Laboratory set out to develop a robust, simple method to analyse levels of these molecules in water from the river Rhine, ground water and drinking water.
