Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air. We investigated the performance of the LC-MS and LC-MS-MS methods in the analysis of isocyanates using the new ASSET™ EZ4-NCO Dry Sampler. We found that the analytical method can successfully reach the quantitation limit for most isocyanates of 5 ng/mL in the final sample when LC-MS-MS analysis was used and the quantitation limit of 10 ng/mL when LC-MS analysis was used. All 11 compounds were well-resolved chromatographically using a 15 cm Ascentis Express C18 column.

Dust monitoring and Sand Storm Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and activities. They reduce visibility, layer on skin and cloths, infiltrate buildings and find their way into food and drinking water leaving a permanent sandy feeling in your mouth. Traditional dust monitoring instruments whether they be purely filter based gravimetric samplers or continuous monitors utilising Tapered Element Oscillating Microbalance (TEOM) or Beta Attenuation (BAM) simply are unable to cope with the high dust loads created by these storms. The filters on these instruments are quickly clogged and no further measurements are possible until a service technician visits to replace filters and filter tapes. In dust storm events this is impossible. Therefore, over the past few years a need for alternate technology which are non filter based, can cope with extremely high dust loads, require minimal maintenance and can operate off solar power has been employed in regions such as the Gobi Desert of China for the continuous monitoring of dust storm events. These instruments have demonstrated that an instrument can measure dust storm events with maintenance performed only once every 12 months. That it is possible to communicate remotely and that these systems can not only provide an early warning for dust events but have the accuracy and sensitivity to be an extremely useful tool in gauging hourly changes of visibility. Infact such instruments have been utilised by a number of EPAs around the world, including all Australian EPAs for the purpose of measuring ambient visibility as well as providing an accurate indication of rising dust events.

Mercury monitoring for on-site remediation

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for multiplexing the Tekran 2537 for real-time continuous on-site monitoring of mercury fugitive emissions. Please contact us for more information on mercury remediation monitoring.

Mercury monitoring for mercury flux measurement

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.

Radionuclide Monitoring for Nuclear Power Plants

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The continuing establishment of nuclear power stations around the world pose unique environmental challenges for their operators. Ecotech provides air samplers to nuclear power plants for sampling of radionuclides. A nuclear power plant`s radionuclide monitoring network enables continuous sampling of airborne particles onto sample filters contained within High Volume Air Samplers. These filters are then analysed in a laboratory in order to screen for any radiation releases. The challenge has always been to obtain a sufficiently large volume through the filter in order to exceed the laboratory methods minimum detection limits. Ecotech`s MegaVol Sampler, samples at a flow rate of between 120-150 m3/hr providing a high flow rate in order to collect a sufficient sample mass for laboratory analysis. The MegaVol will maintain volumetric flow rate at a preset volume until the filter is either changed or overloaded. The MegaVol can be equipped with a 3G modem in order to remotely monitor flow rate and other diagnostic parameters such as temperature, pressure and wind speed and direction.
