Mass spectrometry (MS) is a highly sensitive and versatile analytical technique used to determine the molecular mass, structure, and composition of chemical compounds. By ionizing molecules and analyzing their mass-to-charge ratios, MS provides critical qualitative and quantitative information in pharmaceutical, environmental, biological, and chemical research. Advances in ionization methods, mass analyzers, and detectors have significantly enhanced sensitivity, resolution, and accuracy, enabling the analysis of complex mixtures and trace-level components. This article provides an overview of mass spectrometry, highlighting its principles, instrumental techniques, and applications, particularly in drug analysis, proteomics, metabolomics, and forensic investigations. The integration of MS with chromatographic methods such as LC-MS and GC-MS has further expanded its utility in modern analytical laboratories. Keywords: Mass spectrometry, ionization, mass-to-charge ratio, LC-MS, GC-MS, analytical chemistry, proteomics
Mass spectrometry is a powerful analytical technique that measures the mass-to-charge ratio (m/z) of ions to identify, quantify, and characterize chemical compounds. The process involves ionization of analytes, separation of ions based on their mass-to-charge ratio, and detection of the resulting ion signals. Various ionization techniques, including electron ionization (EI), electrospray ionization (ESI), matrix-assisted laser desorption/ionization (MALDI), and atmospheric pressure chemical ionization (APCI), allow the analysis of a wide range of chemical species, from small molecules to large biomolecules such as proteins and peptides. Mass analyzers, including quadrupole, time-of-flight (TOF), ion trap, and orbitrap, provide high resolution and mass accuracy for detailed structural elucidation. Mass spectrometry is widely used in pharmaceutical analysis for identification and quantification of active pharmaceutical ingredients, detection of impurities, and monitoring drug metabolism. In addition, MS plays a pivotal role in proteomics and metabolomics, enabling the characterization of complex biological samples and the Citation: Michael Thampson.
