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 ...

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. ...

On-the-spot measurement for microbial risk management! Microbial growth in industrial chemicals can present a major problem.· If left unchecked, microbial contamination in raw materials and intermediate products can compromise manufacturing process performance and equipment integrity.· These same sources can also impact final product quality, which if not properly maintained can spoil products while sitting on the shelf.· The best solution is early, accurate detection and proactive ...

Left-turning and right-turning water is the direction of rotation of the rotation of the electron spin of the hydrogen atom. This can be compared with the earth's own rotation (duration 23 hours 56 minutes = 1 day). Each rotation generates a singularly polarizing oscillation, as does hydrogen. This is of biological importance for the quality of the water: clockwise rotating water has positive properties on biological systems. Basically there are 3 groups of waters! ...

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 ...

Air quality monitoring may involve measuring particle mass (PM), particle number concentrations (PN), particle size, or collecting particles for later chemical analysis. Air quality monitoring efforts are usually driven by governmental regulation, but may also be motivated by a neighborhood concern or scientific interest. These measurements are performed by researchers in industries or institutions, but they may also be performed by local advocacy groups. When combined with other information (such as weather data, ...
