  • ASTM D1357 - 95(2011) standard practice for planning the sampling of the ambient atmosphere

    Since the analysis of the atmosphere is influenced by phenomena in which all factors except the method of sampling and analytical procedure are beyond the control of the investigator, statistical consideration must be given to determine the adequacy of the number of samples obtained, the length of time that the sampling program is carried out, and the number of sites sampled. The purpose of the ...

  • Condensable particulate matter - exceptions to the rule

    With the recent revisions to Method 202 for condensable particulate matter (CPM), the US EPA included an exception to the requirement to extract the CPM filter (the secondary filter that is located between the “warm” and “cold” sections of the impinger train).  The exception is subject to the following conditions: The source temperature is less than 85°F; ...

  • ASTM D3268 - 91(2011) standard test method for separation and collection of particulate and gaseous fluorides in the atmosphere (Sodium bicarbonate-coated glass tube and particulate filter method)

    The sodium bicarbonate coated tube filter method provides a means of separating and collecting atmospheric gaseous fluoride and particulate fluoride samples. Since the samples are collected on the dry tube and filter, the fluoride may be eluted with a small volume of eluant (see Section 10 for specific instructions on fluoride elution). Elution into a small volume and the sensitivity of the ...

  • ASTM D3266 - 91(2011) standard test method for automated separation and collection of particulate and acidic gaseous fluoride in the atmosphere (Double paper tape sampler method)

    This test method provides a means of automatically separating and collecting atmospheric particulate and acidic gaseous fluoride samples. Since the samples are collected on dry tapes, the samples are in a form which allows elution of the fluoride content with a small volume of eluent. Consequently, the method allows analyses of air samples taken for a time period as short as several minutes. ...

  • $3 billion market for air pollution monitoring, sampling and process control

    The world market for stack continuous emissions monitors (CEMs) will be $900 million this year. However, if one takes into account the additional revenues for ambient monitoring systems, intermittent stack sampling and process control using pollutant analyzers, the market is above $3 billion. This is the latest forecast in the McIlvaine Air Pollution Monitoring and Sampling World Markets. Some ...

  • New sample gas probe for operating temperatures up to 280°C

    In the process of extractive gas analysis, it is essential to stabilise the operating temperature of the sample stream above a certain level. If the sample gas would undercut these limits, acids could fall out or chemical reactions could take place, e.g. salt or other crystals may be formed. Unexpected acid condensate could increase the corrosive property of the gas or the precipitation of solids ...

  • New Odor Sampling Procedure for high humidity air flow from food or feed dryers/coolers

    Special odour sampling procedure with nitrogen dilution has been developed by Uniqair and Purdue University Odor Lab for odour samples with high humidity from dryers and coolers. The nitrogen will preserve the odor and prevent condensation for more accurate odor concentration test results. Unlike VOC testing, the odour lab is utilizing human noses of screened panel members with odor sensing ...

  • Air pollution can damage DNA in three days

    Inhalation of some particulates can cause some genes to become reprogrammed, affecting the development and outcome of cancers, Italian researchers said. Dr. Andrea Baccarelli of the University of Milan enrolled 63 healthy subjects who worked in a foundry near Milan. Blood DNA samples were collected on the morning of the first day of the work week, and again after three days of work. Comparing ...

  • Monitoring how aerosols affect climate change

    Monitoring aerosols is of growing interest especially as current research has indicated that fine particulates are linked to not only adverse health effects but also climate change. It has been known for some time that fine particulate matter (PM2.5) has been widely linked to adverse health effects such as asthma. Approximately 70% of particulate mass generated by, for example, bush fires is less ...
