Overcome Element Analytical Challenges with Environmental Samples Using ICP-OES
While environmental analysis applications are often considered easy, they are in fact rather challenging. In any given case, the matrix composition, the amount of totally dissolved solids in the final solution, and the concentration ranges of the elements can all vary considerably. Variations from sample to sample are also not uncommon.
Inductively coupled plasma optical emission spectrometry (ICP-OES) analyzers with axial plasma observation are the instruments of choice for this kind of elemental analysis work. They provide the sensitivity required for the determination of trace metals. However, this technology also suffers strong influences that can interfere with clear analysis. Since the entire channel is visible, all phenomena present in the excitation zone — including the plasma tail and bottom — are within the light path.
This webinar presents challenges related to environmental work, refers to relevant undesirable effects, and suggests solutions for how they can be eliminated or avoided. As an example methodology, it will discuss using environmental analysis according to the CLP protocol, and cover some available technologies.
