Inductively Coupled Plasma (ICP) spectroscopy is used to analyze samples to study their chemical composition. It is a highly sensitive tool invaluable in numerous applications, including trace element analysis in liquid samples. However, one problem in analytical chemistry ICP analysis is that matrix effects can occur, resulting in significant errors in the results. This is where the standard addition method comes into play, a quantitative analysis technique used to minimize matrix effects that interfere with analyte measurement signals. In this blog post, we look at matrix effects and how standard addition testing ensures accurate results in ICP analysis.
Matrix Effects in ICP Analysis
Matrix effects in ICP analysis refer to interferences caused by the presence of other elements or compounds in the sample matrix. These effects can significantly
