Chemical Contamination
Chemicals play a major role in everyday life. They are used extensively throughout industrial sectors as well as in private residences. Products from the chemical industry provide the foundations for nearly all manufacturing activities. They are found in the making of a wide variety of products ranging from pesticides to man-made fabric, and even cosmetics.

Gas Detection Technology
Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital, because melting of permafrost could cause a dangerous climate tipping point.
There can be few more challenging environments for monitoring gases, but PhD researcher Martin Brummell from the University of Saskatchewan has successfully employed a sophisticated gas analyser to do so in the High Arctic of Canada.
Dr Andrew Hobson from Quantitech explains.

Uncertainties In Climate Science
Climate Change is one of the biggest concerns of today and yet there remains much uncertainty about the science, the extent being expressed in the Intergovernmental Panel on Climate Change (IPCC), Fourth Assessment Report (AR4) (2007) thus:
The complexity of the climate system and the multiple interactions that determine its behaviour impose limitations on our ability to understand fully the future course of Earth’s global climate. There is still an incomplete understanding of many components of the climate system and their role in climate change.

Wastewater Sample Stability
Introduction
At the point of analysis, it is essential that a sample is still representative of the whole from which it was taken. This is an obvious statement, but one which can often be overlooked. Regardless of how modern the analytical instrumentation, or how sophisticated the extraction process, or how experienced the operator, all of this is irrelevant if the concentration of the target analyte has changed since the sample was taken.
