  • Air monitoring equipments for workplace and personal exposure monitoring

    Many occupations involve the use of hazardous substances or processes, where pollutants may be ingested, inhaled or absorbed through the skin. General ambient pollutants can also have health implications in otherwise non-hazardous workplaces. Occupational exposure limits regulate many pollutants based on an eight-hour working day. Personal exposure assessments can be made over an eight-hour period (Time Weighted Average (TWA) exposure) using our simple to use monitoring equipment.

  • Pollutant monitoring for the manufacturing industries

    Ormantine`s air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range. Ormantine USA`s many solutions have applications from personal exposure monitoring to long term fence line monitoring studies.

    Waste water treatment plants Personnel Safety & H2S filter management

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

    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

    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.
