Historically, inductively coupled plasma (ICP) spectroscopy has been used for the analysis of multiple analytes with excellent speed, sensitivity and large linear dynamic range. Early ICP instruments used photomultiplier tubes for the analysis of single wavelengths, one at a time. Introduction of solid state detectors allowed for the simultaneous acquisition of all wavelengths and background information resulting in data-rich analyses. However, even with these advances, most users still only uti
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.
High-purity acids and reagents are critical to controlling the analytical blank, the “Achilles heel” of trace analysis, and to improving ICP-OES and ICP-MS detection limits. Reagent purity, cleanliness of the materials used in sample preparation, the laboratory environment, and the skill of the analyst are all factors that contribute to contamination. In this application note, Milestone presents the duoPUR and subCLEAN systems for cleaning reagen
