The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards. Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its inhabitants.
In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to allow...
Within the field of gas analysis much time is spent looking at the accuracy and uncertainty in the detection technique. However, without appropriate sample handling, what you are measuring could potentially bear little or no relation to your original sample.
Quantitative determination of the total mercury content in filtrates of wash-off samples from the surfaces of walls, floors, equipment, and other facilities of m anufacturing areas is an effective method for the occupational safety monitoring.
Particle size, particle concentration and other physical characterization analyses are critical to many environmental applications. Regulatory agencies in the environmental sphere demand strict compliance to standards and discharge regulations. Physical testing of samples for parameters such as particle size and concentration can give insight to the process control engineer on how effective and compliant a discharge handling system is operating. Particulate loading from both air emissions and waste water discharge...
The effect of potential interference from other constituents of sea water was studied, including sodium, chloride and potassium. It was found that pre-concentration of the sea water was not necessary prior to analysis. A filtration of the sample was only necessary if sample contained suspended material.
The continuing establishment of nuclear power stations around the world pose unique environmental challenges for their operators. Ecotech provides air samplers to nuclear power plants for sampling of radionuclides.
Brick kilns, as well as other plants such as ceramics manufacturers and fertiliser producers, are a major producer of hydrogen fluoride (HF) emissions. HF is highly reactive gas and seriously damaging to human health, so has strict emissions limits imposed by legislation. In addition to the effects to humans, emissions have been found to damage crops and fruit trees, as well as the general environment. The brick industry strives to reduce the amount of HF emissions and numerous projects have been carried out into...
Several different techniques can be used for sample digestion and extraction of sodium and/or potassium: oven ashing, perchloric acid ashing, extraction by boiling and acidification with HNO3 as well as extraction by homogenisation in 2% trichloroacetic acid (TCA).
Niton analysers facilitate direct surface testing for lead paint, testing for lead in dust wipes from surfaces, testing the lead content of soil in the surrounding area (containment) and the testing of lead content in filters from respirators or volume air samplers for worker/public protection.
A number of methods have been reported for the measurement of calcium in biological materials by flame photometry or titration. This method employs trichloroacetic acid (TCA) to precipitate the proteins and has been found to be adequate to extract all of the calcium from tissue samples. Sodium, potassium and phosphate caused no significant interference and calcium concentration in the range of 0 to 2 µg/ml is readily determined.
HI-Q Environmental Product Company provides air sampling instrumentation & systems for several niche applications in a number of disciplines in the broad area of `Life Sciences`. In the Biomedical, Chemical, & Pharmaceutical industries, HI-Q has marketed instrumentation for certain applications for many years. Our ambient, in-door breathing level air samplers, commonly known in the industry as `Goose-Neck` or `Giraffe` air samplers have been instrumental in analyzing workplace exposure. HI-Q has also...
Sometimes an `off the shelf` water quality monitoring product is just not available and it is necessary to engineer a complete bespoke monitoring solution. System integration demands a diverse range of abilities. PPM is experienced in designing the correct suite of instrumentation combining manufactured, distributed and factored products.
