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.
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...
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.
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.
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).
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.
Metalmembranes offers a unique laboratory filtration solution for a variety of filtration applications for instance bacterial concentration before analysis, sample preparation before (HPLC) analysis etc. The membranes have a pore sizes of 150 nm (Aluminum) and 15 nm (Titanium).
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.
PTL`s service to the food and beverage industry is consultative and exacting. Manufacturers need to identify and control particle size distribution and other physical properties of food powders and emulsions in order to control the quality of the food_beverage_particle_testing_analysisfinished product. Factors such as appearance, taste, “mouth feel”, processing and handling are all affected by physical characteristics including particle size, particle shape, surface area, thermal properties, powder flowability,...
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.
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...
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...
