Significance of Mass spectrometry
Mass spectrometry, as defined by the provided texts, is an analytical technique used to identify and quantify substances. It operates by measuring the mass-to-charge ratio of ions, providing information about molecular weight, structure, and composition. This technique is widely applied across various fields, including Ayurveda, science, and health sciences. It's utilized to analyze compounds in herbal extracts, identify drug impurities, and characterize complex mixtures like metabolites and essential oils, often in conjunction with chromatography.
