  • Whatever your discipline, there is a liquid scintillation counter in the 300 SL range to suit every need

    Working in life science research, radiochemistry or radiation protection? Then the standard model 300 SL is the perfect solution. Compact, lightweight and easily integrated into small laboratories this model offers optimum counting efficiency of samples without any external or internal standard source of radioactivity. However, if you are dealing with more challenging samples, such as those often ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • UV Ballast Water Treatment Close to US Approval

    Shipowners have found it increasingly difficult to comply with ballast water treatment regulations in the US. But there’s good news on the horizon thanks to DESMI’s newest UV-based solution Ultraviolet radiation (UV), which counters microorganisms by rendering them unable to reproduce, is the preferred method for today’s ballast water treatment systems. This robust and reliable ...

  • Long optical paths of large aperture

    THE measurement of the vapor phase spectra of compounds having high boiling points presents an experimental problem that may be solved either by heating the absorption cells or by making them very long. In the infra-red region radiation from the hot gases in heated cells decreases the accuracy of absorption measurements. If only a small amount of sample is available, the only possibility is to ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

  • A novel spectrometer design for process and handheld infrared spectral measurements
