air monitoring procedure Applications

  • Air quality monitoring for regulatory purposes

    Air quality monitoring for regulatory purposes requires instrumentation, systems and procedures that meet international standards such as those described by the USEPA, MCERTS or the European Union. Ecotech offers solutions that meet this criteria.

    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

  • Noise monitoring for airports

    Airports, small and large, use noise and operations monitoring systems to reduce the noise of flight operations in the surrounding community.  Noise monitoring is generally used to evaluate noise abatement programs and to develop aircraft departure and arrival procedures that minimize the impact of aircraft noise based upon altitude, flight path, and time of day.  Noise monitoring is linked with radar tracking so that specific aircraft can be identified when noise limits are exceeded and so operational requirements can be enforced.
    Larson Davis provides noise monitoring systems to airports, consultants, and system integrators with the technology and support to make a successful program.

    Gas monitoring instruments and systems for stack testing

    Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives and regulations set. Two major parts of this on-going quality assurance cycle are the QAL2 and AST procedures. A test laboratory performs tests on the systems on-site, and determines whether the systems fulfill the set requirements or not.

    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.

  • Air and particule sampling for the oil and gas industries

    Ormantine offers a wide range of products and services to meet the array of different needs that arise in the oil and gas industries. Volatile Organic Compounds (VOCs), benzene, and other compounds are released during drilling, hydraulic fracturing (fracking) and other extraction procedures. Monitor NOx emissions from heavy duty equipment, particulate matter, and ground level ozone, the formation of which is contributed to by VOCs from processing, transportation, and storage of oil and gas.
