Spectroscopy in Space [Mar 2010]
Getting best value from laboratory biodegradability testing by avoiding some common pitfalls.
Methods of Soil Analysis - A summary of some of the many methods of soil analysis [Dec 2009]
Soils are an extremely complex matrix to analyse, particularly on contaminated sites - the actual soil matrix can vary from a sand (silica) to limestone (calcium carbonate) to clay (complexed minerals), or a mixture of many. In addition to this, the range of contaminants varies from fairly innocuous construction materials to toxic gasworks waste to highly toxic pharmaceutical waste/ mercury/explosives, etc.
Spectroscopic Techniques [Jun 2009]
Nuclear magnetic resonance (n.m.r.)
Introduction
In n.m.r. a radio frequency is applied to the substance of interest together with a progressively increasing magnetic field. When the magnetic field is such that the separation of the energy levels it induces corresponds to the energy of a photon of the applied radiation there will be absorption of the radiation and therefore a signal. Nuclei in chemical compounds are not ‘bare’, and the molecular environment of a nucleus influences the spacing of the energy levels and hence the magnitude of the field at which a signal will occur. This is called chemical shift and is of the order of parts per million of the applied field.
HSI's Gas Detection FORUM [Jul 2008]
The fourth of our five manufacturers forums for 2008 concentrates on the field of gas detection. Once again we approached manufacturers from around the world with the same questions and these are the answers we received.
Spectroscopic Techniques: Atomic Absorption [Jun 2008]
Electromagnetic radiation, of which solar flux is composed, encompasses visible light but also extends far beyond it to shorter and to longer wavelengths than our eyes can respond to. When light is passed through a prism it is resolved into components, as is well known from studies of elementary physics or, equivalently, from observation of a rainbow.

Recent Improvements in Chromatography [Mar 2008]
Improved instrumentation, greater sensitivity and faster analysis
Chromatography is one of the main tools of the environmental analytical chemist in providing detailed information on hundreds of different organic compounds which may be present in the environment. A general introduction to chromatography was provided in this journal last year (Dec 06/Jan 07 issue), giving a description of the basic principles of chromatography and a number of different techniques available for use in the modern laboratory.
State-of-the-Art Spectroscopy [Mar 2006]
Protecting our environment is the most important strategy for maintaining a high quality of life for current and future generations.
