Determination of the pH value provides information about the acid or base action of the soil solution. This in turn is enormously important for the nutrient supply and microbial activity of the soil. For example, many metals (trace elements) are considerably more mobile in acidic soils. If the soil pH values are very low, toxic levels can soon be reached and these can damage the roots of plants. On the other hand, excessively high pH values quickly lead to a shortage of trace elements because of immobilization.<...

The pharmaceutical industry is one of the most regulated industries. Contaminants in drug products are examined throughout the manufacturing process, since their presence affects drug stability, behaviour and toxicity. Therefore, regulatory bodies such as the European Medicines Agency (EMEA) and the American Food and Drug Administration (FDA) strictly enforce continuous and ongoing analysis of organic or inorganic impurities from raw materials, excipients and Active Pharmaceutical Ingredients (API) through...

In nature, the chemical elements can be represented by more isotopes, or atoms of the same element, characterized by a different number of neutrons in the nucleus. When the proton / neutron ratio does not exceed that value likely to upset the balance of the atom, resulting in the phenomenon known as stabilization of radioactive decay, the isotope is called stable. That is, over time, will not tend to emit energy and sub-nuclear particles to gain energy stability, giving rise, at the end of the process, the...
