While two analytical methods and systems are necessary for the digestion in a calorimetric bomb and the subsequent detection of the halogens (e.g. by means of IC), in this application note, Analytik Jena presents a method which has the advantage of combining digestion and detection in only one analytical step in a single system.
In this application note from Analytik Jena, two series of digestion of the certified reference material (CRM) soil (NCS DC 73325), China National Analysis Center for Iron and Steel, Beijing, China, were performed. In each series, a different acid mixture was applied. The main objective of this investigation was to provide an accurate analysis method for evaluating the anthropogenic impact of a soil following the EN 16174:2012 regulation.
In this application note, Analytik Jena demonstrates the capability of the ICP-OES to quantify sulfur and other elemental contents in biodiesel samples following ASTM D4951, EN 14538, and ISO 20424 (for sulfur) methods. This allows for an economic analysis covering all critical elemental parameters in one run.
