Ammonia Sensors and Their Applications [Sep 2009]
The key to success is understanding the monitoring environment, and the specific benefits and limitations of the sensors selected
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.
Dry Chemical Odour Scrubbers [Sep 2008]
The principle of distributed odour control
Dry chemical scrubbers are uniquely suited for use in collection system pump stations and in waste water treatment plants for the control of odours. They are inherently simple in their operation and function continuously without operator attention for extended periods of time. This type of scrubber, through the use of specialised gas-phase or dry-scrubbing air filtration media types(medias), is essentially able to achieve the complete removal of odours without the need for additional dilution air.
Getting the Measure of Methane [Jan 2008]
Geotech looks at the world of biogas with focus through two case studies
Methane makes money. It generates energy revenues, carbon credits and is part of bio-treatment sludge processing. In most of the world it has only just begun. Measuring what we are doing and being responsible with this potentially damaging greenhouse gas makes good sense.

VOC Detection and Measurement Techniques [Jun 2006]
Outlining the application of laws surrounding Volatile Organic Compounds
The Unseen Threat of VOCs [Mar 2005]
How photoionisation detection is used for worker protection, fenceline monitoring and environmental remediation.
Organic compounds are chemicals that contain carbon and are found in all living things. Volatile organic compounds, often referred to as VOCs, are organic compounds that easily become vapours or gases.
