Whether it's organic aerosols, metal particles suspended in air or fine dust generated in construction, mining and manufacturing - all of these air contaminations must be monitored to protect workers and the surrounding environment.
Analysis of Airborne and Waterborne Metal Particles on Filters by XRF
Airborne metals collected on filters during welding, construction, mining, manufacturing, and paint removal must be monitored for heavy metals and other dangerous elements to protect workers and the surrounding environment. Similarly, waterborne metals collected on filters must be analyzed to protect people, animals, and the surrounding environment.
XRF is a fast, nondestructive technology for elemental analysis of heavy metals and other trace elements collected on filters for environmental assessments.
Monitoring Silica Workplace Dust Exposure by XRD
Lung cancer and other health problems are known to be related to occupational exposure to breathable crystalline silica (SiO2). As a result, silica dust, or free silica, is the second most frequent cause of cancer in the workplace after asbestos.
X-ray powder diffraction (XRD) effectively distinguishes the polymorphs of crystalline silica (quartz, cristobalite and tridymite). In addition, XRD provides an explanation for interference with other minerals that may be present in the workplace.
Monitoring Air Polluting Sulfur from Ship Fuel with Portable XRF
The International Convention for the Prevention of Pollution from Ships (MARPOL) carriage ban on non-compliant fuel oil went into effect on March 1, 2020. Quickly and accurately measure sulfur in marine fuels to ensure bunker fuels meet regulations in Emission Control Areas and other restricted locations. This method follows ASTM D4249 higher concentration range of 0.1 to 5.0% Sulfur in Fuel and ISO 8754:2003. Suppliers, engineers, ship captains and inspectors can use our portable XRF Sulfur Measurement solutions at service labs, supply stations, on docks, in ports, and even aboard barges and ships.
Ambient Air Quality Monitoring of Sulphur Compounds
The presence of Sulphides in ambient air is an environmental hazard. The detection of Sulphur compounds at trace levels is critically important through ambient air quality monitoring. Monitoring Sulphur compounds is commonly done in industrial emissions testing and environmental monitoring at sewage treatment and landfill sites. Compounds such as Carbon Disulphide, Methyl Mercaptan, Ethyl Mercaptan, Dimethyl Sulphide, Propanethiol, Ethyl Sulphide, Dimethyl Disulphide and Butyl Mercaptan are volatile compounds that require thermal desorption as a means of analysis.
Thermal desorption is a technique that provides a trace level analysis through both offline and real time monitoring of vapor changes in the sampling environment.
This application note describes environmental monitoring of low-level Sulphur in ambient air through thermal desorption gas chromatography.
The PG-300 is a compact and lightweight stack gas analyzer that can simultaneously measure up to five separate gas components. Its capability of providing precise measurement has been proven for field measurements and also for laboratory applications.
Function Control Unit with Mass Flow Controller.
The AFCU-360M operates as an accurate function control unit for several analyzers of one emission measuring station.
The portable calibration unit ASGU-370TS is designed for the dynamic and continual manufacture of zero and span gas to perform all ongoing quality control procedures according EN Norms. To prepare various span gas concentrations the unit uses technologies like dilution, permeation, Gas Phase Titration.
The sampling unit is responsible for suction air from ambient and to distribute this air without any changing to the gas-monitors. The HORIBA sampling unit is designed according ÖNORM-M5852 Type A. So, an air flow monitor will give alarm information when the flow is too low.
The APDA-371 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter), using the industry-proven principle of beta ray attenuation.
The portable Counter Top XRF (CTX) is small, light-weight, safety-interlocked, and battery operated. At 7 kilograms in weight, the self-contained CTX is truly portable, and has a small footprint of only 14 cm in width. Up to 48 elements analyzed per calibration.
The environmental monitoring system EM 27 is an open path Fourier Transform infrared (FT-IR) spectrometer, designed and optimized for remote sensing of chemical substances in the atmosphere. With its high sensitivity, mechanical stability and speed the system is ideally suited for a wide range of applications, from industrial air quality monitoring to academic research in the field.
