Featured OEA applications

The importance of soil and plant testing has increased in the last few years, as many of the traditional methods are no longer suitable for routine analysis, due to their time consuming preparation and the use of environmentally hazardous reagents. Also, the analysis of the chemical composition of fertilizers is important in agronomy for research and quality control purposes. One of the tests used in the production process of fertilizers is the determination of the nitrogen content. For these and many other applications the organic elemental analysis technique fulfills the need for an efficient analytical technique for characterizations of CHNS/O of environmental samples.

Food market globalization demands more accurate quality control of product characteristics, in order to protect commercial value, to safeguard consumer health and manufacturer reputation. Official regulations establish protein content and labeling requirements which enable consumers to compare price and quality. For this reason the organic elemental analysis technique, based on the Dumas (combustion) method is recognized by international associations as an alternative to the classical Kjeldahl method, for more precise, compliant and automated analysis.

In a typical production process of lubricants, oils, polymers and plastics, carbon black etc. the elemental content is periodically monitored and tested for quality control. The amount of the industrial sample content is often a requirement for the calculation of other by-products, which can be pollutants or harmful to the environment or human beings. In this case organic elemental analysis technique enables to comply with the request of international methods for reproducibility among the other standard requirements from modern laboratories.

The chemical characterization of organic compounds plays a very important role in all of the processes of synthesis, separation, purification and their structural identification both for research and quality control purposes in pharmaceuticals. One of the tests used in the production process is the determination of organic elemental composition which is periodically monitored for the characterization of materials. Rigorous quality control begins with the suppliers of the raw materials. Therefore, organic elemental analysis technique enables accurate and fast analysis with excellent reproducibility.
