Laser Ablation Inductively Coupled Plasma Mass Spectrometry as a Powerful Tool for Spatially Resolved Analysis: An Experiment for Undergraduate Analytical Chemistry Laboratory
Journal of Chemical Education, v100 n5 p1973-1979 2023
A new experiment using laser ablation with inductively coupled plasma mass spectrometry (LA-ICP-MS) was designed for chemistry undergraduate students. While most analytical methods only provide information on the amount of the analyte, LA-ICP-MS allows extra information on the distribution of the element in the sample. Because it achieves excellent limits of detection (sub µg·g[superscript --1]) and high spatial resolution (micrometer scale), it is a powerful technique for imaging any sample. A thin section of mouse tissue was used as a model sample to demonstrate these abilities. The student's task was to determine the distribution of the essential elements Zn, Cu, and Pt (Pt introduced into the tumor tissue from the cytostatic drug (cis Pt)) and quantify their amount.
