carbon testing Applications

  • Measurement solution for on-line carbon bed system

    Commonly, activated carbon beds are used as abatement systems on plant, with emissions being reduced by adsorption onto the bed. The efficiency of any abatement system is critical to its operation, not just in ensuring emissions are reduced as much as possible, but an efficient bed has cost savings for the operator.

    Industrial solutions for the carbon dioxide (CO2) lasers

    Carbon Dioxide (CO2) lasers are high power lasers, usually used for cutting of ferrous and non-ferrous metals. High-performance gas flow control is a key requirement for achieving high cutting performance with CO2 lasers. Gas flow control plays an important role for mixing key gases at a number of locations with a CO2 laser: Beam Generation: The gas mixture used as the emitting medium usually consists of CO2, He and N2. Most laser manufacturers specify a minimum required purity for the beam generation gas mixture, which is typically > 99.99%. A highly-accurate gas mixing control is therefore necessary, either for production of pre-mixed gas cylinders, or for in-situ mixing within the laser unit.

    Measurement of hydrogen sulfide & carbon disulfide in air for continous emission monitoring

    The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the H2S, CS2, and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. H2S and CS2 are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

  • Haze Monitoring

    The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.

  • Filtration for water testing

    Chemical purity of water is assessed for a wide variety of different chemicals depending on the type of water and applicable local legislation. 

    Chemical analysis of water can include testing for nitrogen compounds, dissolved heavy metals, and total and dissolved organic carbon.

    Common water monitoring applications include:

    • Determination of suspended solids in waterusing for example glass fiber filters.
    • Chemical analyses of for example heavy metals, dissolved organic carbons (DOC), and ions.
    • Microbiological analyses using membrane based microfiltration methods

  • Air Monitoring

    The recent COP 21 meeting reexposed the need for global coordination to monitor Green House Gases (GHG) as well as emissions of ChloroFluoroCarbons (CFC). Networks of sensors have been deployed over the Earth to measure concentration of gases such as methane, carbon monoxide, ethane, carbon dioxide, nitrous oxide, nitrogen oxide and dioxide (NOx)… Such task requires instrument with not only ultra high accuracy but also ultra high precision. Our QCNose Instruments  have been designed for such operations where reliablity combines with performances.

    Oxygen monitoring from aerobic and anaerobic for biodegradation tests

    Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.

  • CH4 Monitoring in Air

    CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4 analyzer that is able to provide continuous monitoring is a perfect solution for this.

  • Laboratory Ion Analyses

    Our single ion and multi ion kits allow for real-time laboratory analysis of one to six ions simultaneously with one probe. These ion sensors along with the reference electrode are solid state which allows for easy handling, storage and maintenance. No filling solutions nor buffers are required. The sensors are based on carbon nanotube technology allowing for reliable and reproducible measurement of ions in liquids.

  • CO2 / CO Monitoring in Air

    CO (carbon monoxide) and CO2 (carbon dioxide) are generally measured to ensure process control. CO2 is the desired product and CO is undesired in combustion since it will explode in high enough concentrations. CO2 and CO concentrations can also be used to determine other process-specific efficiencies. Continuous emissions monitoring equipment that can be calibrated as a CO and CO2 analyzer is thereby essential for process control.

    Instruments and analyzers for spectral DNI measurements

    Where the pyrheliometer is most suitable to quantify the total DNI of the solar spectrum. The spectroradiometer gives details about the energy distribution which is important for PV or CPV cell research. The solar spectrum wil change with the angle of incidence and its path through the atmosphere. Photons wil be reflected, scattered or absorbed. Big absorbers of infrared irradiance are water vapor, carbon dioxide, and ozon.

    UV fluorescence technology for raw water intake monitoring industry

    Naturally occurring organics in raw water are typically removed with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when generic organic material is present but cannot differentiate between natural organics, such as algae or decomposed plant matter, and hydrocarbons. Using UV fluorescence technology, a properly configured TD-4100XD can alert operators to upsets caused by hydrocarbons such as gasoline, diesel, fuel oil, and crude oil.

  • Drinking water solutions for the TOC removal efficiency

    Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.
