  • Gas detection analyzers for coil coating industry

    Coil Coating is a high-temperature solvent vapor monitoring application in which rolls of aluminum or steel are coated with a color finish, oven cured to desired specs and sold to makers of cans, rain gutters, home appliances, building & automotive products and other fabrications. Coil coating requires the use of our PrevEx Flammability Analyzers to monitor the flammability of the solvent vapor driven off during the drying process. PrevEx analyzers accurately measure solvent mixtures and can withstand the temperatures required to prevent sample clogging in coil coating plants.

  • Gas detection analyzers for pulp & paper mills

    Flammable non-condensible gases (NCG’s) are byproducts of the wood pulping process. Health and pollution regulations prohibit the release of these gases into the atmosphere. They are usually eliminated by passing them through an incinerator or by using them as fuel in the burner of a boiler or kiln. The incinerator, boiler or kiln however can be damaged by NCG’s which have built up explosive levels. Pulp mills require the use of our PrevEx Flammability Analyzers to monitor the NCG stream and detect and divert these dangerous concentrations before they can cause damage and shut down the mill. The PrevEx analyzers accurately measure the total concentration of flammable gases present in the NCG sample. Their high sampling speed dramatically improves response time—an important factor in pulp mill applications.

    Gas monitoring instruments and systems for process NOx measurement

    Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

    RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

    A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages. The measuring method is based on thermal atomization of mercury from a sample using a PYRO-915+ attachment and its consequent determination by flameless AAS with Zeeman background correction using the RA-915M mercury analyzer. The total time needed for determination of mercury is not longer than 2 minutes. RA-915+/915M is compliant with US EPA 7473 and ASTM D7622 methods.

    EDXRF spectrometers for cosmetics industry

    During the manufacturing process, cosmetic products need to be chemically analyzed to ensure conforming to product specification and safety regulations, as well as achieving cost-effectiveness in the manufacturing process. Using ED-XRF allows measuring a wide range of elemental concentrations such as C(6)-Fm(100), without a need for sample preparations(heating or destroying the sample). Samples can be measured in the form of loose powders or powders pressed into pellets, and are made ready for measuring within seconds.

  • Laser detection solutions for water-quality monitoring

    The technology of Spectral Fluorescence Signatures (SFS) is a very sensitive and selective tool to monitor many industrial processes on site and in real-time. The SFS analyzer series – SFS-Scanner and Instant Screener spectrofluorometers - are capable of detecting target substances even in complex mixtures without any pre-treatment of the samples.

  • Quantitative Analysis of Steel Using Laser Induced Breakdown Spectroscopy (LIBS)

    For steel analysis, LIBS is ideal for rapid QC (quantitative analysis and detection of contaminants) for raw materials in production, and to check the elemental composition of finished products. LIBS also offers the ability to analyze slag samples that can lead to the recovery of precious metals lost in the steel production process.

  • Precision moisture analysis instruments for fast, accurate solids analysis for wastewater

    Computrac moisture, solids and ash analyzers are able to quickly and easily determine solids content of cakes, slurries and sludge samples for the wastewater, hazardous waste and landfill industries. Identifying the optimal solids content of these byproducts of the treatment process can provide significant cost savings on chemical additives, haulage and incineration. Computrac analyzers are easy to use and their rugged and reliable design means that you’ll get accurate results whether they’re in the plant or in the lab. They can also be used to determine whether or not total solids content in landfills is consistent with state and local regulations.
