What are the matrix effects that affect laser induced breakdown spectroscopy?4 answersMatrix effects that affect laser-induced breakdown spectroscopy (LIBS) include severe matrix effects and high signal uncertainty. These matrix effects directly influence plasma parameters, spectral intensity, and the quantification performance of LIBS. The superposition of matrix effects and signal uncertainty can lead to variations in spectral emission lines, making them highly variable. The heterogeneity of granular materials like soil can also contribute to matrix effects, as the microscale heterogeneity of soil samples can result in highly variable spectra. Moisture in soil samples can also interact with certain elements, such as iron minerals, leading to different estimation results. To address these matrix effects, methods such as data selection based on plasma temperature matching have been proposed to reduce both matrix effects and signal uncertainty, improving the quantification performance of LIBS.
How does the matrix effect affect the results of an experiment?5 answersThe matrix effect can have both positive and negative impacts on the results of an experiment. It can lead to errors in quantification, affecting the detection capability, precision, and accuracy of the analysis method. The matrix effect can cause signal suppression or enhancement, depending on the specific compounds and their interactions with the matrix components. In some cases, the matrix effect can be corrected using an internal standard, but for certain analytes, this may not be sufficient.
