Mass spectrometry (MS) is a cornerstone in toxicological analysis due to its high sensitivity, specificity, and ability to analyze complex mixtures. When coupled with separation techniques like gas chromatography (GC-MS) or liquid chromatography (LC-MS), it can detect and quantify trace levels of toxic substances in biological samples. MS helps in identifying unknown compounds, determining molecular structures, and providing quantitative data, making it indispensable in forensic toxicology, clinical toxicology, and environmental toxicology.
