Case study - Monitoring landfill gas

Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

Total solution: Gas and particulate analysis in Cement industry

Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

FTIR gas analysis improves container safety

Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

Gas cell selection for analysis of electronic gases

APIMS and FTIR remain the preferred analytical tools for monitoring impurities in the electronic specialty gases used by the semiconductor industry, although other tools such as CRDS are currently finding application in selected cases. FTIR spectroscopy offers the advantage of the simultaneous measurement of all gaseous species that exhibit dipole moment changes during vibrations at ...

Functional nanostructures from clusters

Functional cluster-assembled nanostructures with original structures and properties are prepared using the Low Energy Cluster Beam Deposition method (LECBD). This technique consists in depositing supersonic clusters produced in the gas phase using a combined laser vapourisation-inert gas condensation source. Low energy clusters with typical sizes ranging from ∼1 to a few nm are not fragmented ...

Reaching underground resources

Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

Why monitor dust in the workplace?

Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the ...
