  • Opacity monitoring for continuous emissions

    The history of air pollution regulation dates back as far as the 13th century when in 1273, Edward I (Longshanks) of England prohibited the burning of sea coal in London. The smoke produced by its combustion was considered detrimental to human health. By the late 19th and early 20th centuries, regulations were being passed that sought to control air pollution predominantly for smoke and odour control. Traditionally, regulators were concerned with the visual impact of the discharge from a stack or chimney. Therefore, emission limits were expressed in terms of colour or opacity. Modern methods for opacity measurement still use the darkness of the stack gases to measure the amount of smoke or dust emitted within the exhaust gases.

    Title : Preliminary Sampling Methodology and Analytical Procedures for Ambient Sulfur Hexafluoride, Corporate Author : ARMY MEDICAL ENVIRONMENTAL ENGINEERING RESEARCH UNIT EDGEWOOD ARSENAL MD Personal Author(s) : Luckan,Susan K. ; Cooper,William J. Report Date : JAN 1973 Pagination or Media Count : 23 Abstract : A preliminary evaluation of techniques of sampling and gas chromatographic analysis for low levels of sulfur hexafluoride was conducted to determine the most feasible method for available equipment. Using a Tracor MT-150 gas chromatograph equipped with Nickel 63 electron capture detector and polarized dc voltable, it was possible to detect sulfur hexafluoride at a concentration of 0.06 ppb with a 5A molecular sieve column and nitrogen carrier gas, without preconcentration of the sample. Also, a comparison of glass and Saran sampling materials proved that no detectable loss of the tracer gas resulted with the Saran bags (between 6 ppm and 0.06 ppb SF6

  • Particulate monitoring for continuous emissions

    With the advent of specific process emission limits being defined, continuous particulate monitoring has become a regulatory requirement for many industries. smoke stack #1Particulate monitoring requires the measurement of the mass concentration of particulate matter in stack emissions to atmosphere. There is no known method of continuously measuring particulate concentration by direct measurement and therefore, all continuous particulate measurement methods are inferential. Each method involves the measurement of a parameter related to particulate concentration and then requires a calibration to be determined to convert the measured value into one of particulate mass concentration.

    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.

    Testing Fume Hood Flow Dynamics using SF6 as a Tracer Gas

    A safe laboratory environment requires an effective method for clearing toxic material from fume hoods. Since all handling of toxic materials is completed in these hoods, it is critical to have a procedure to evaluate their operation to assure adequate protection for laboratory workers. The InfraRan Specific Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood efficiency in accordance with ASHRAE and other standards. Manufacturers identify the flow dynamics (factors that affect air flow in the hood and performance with air) using the ratings AM (as manufactured), AI (as installed), and AU (as used). A fume hood evaluation conducted under its operational environment is critical, as these tests will indicate any installation shortcomings as well as direct workers in proper laboratory hood techniques.

    Mercury monitoring for mercury flux measurement

    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.

  • Cost effective, real-time pollution monitoring networks

    Ambient air pollution is a continuous problematic since many years, and the various organizations in charge of air quality monitoring work constantly on how to improve their structures and gain the most accurate and reliable data possible. Indeed, the changes in mentality and therefore in urbanism development for example, implies an access to the data faster and at multi-location level. Air quality monitoring reference stations used nowadays measure with an extreme accuracy in located areas, but requires a lot of energy, financial investment (to purchase and to maintain) and space. It is not easy then to move them easily, or to multiply them to cover more accurately the area. Cairsens sensors, installed under Cairtub or Cairnet formula perfectly address this problematic: autonomous, very compact, cost effective and ready to install systems, feature a viable alternative or or a complementary measurement methods to the existing reference networks.

  • Radionuclide Monitoring for Nuclear Power Plants

    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.

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

    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.
