Abstract

Liquid Chromatography-Mass Spectrometry (LC-MS) stands as a cornerstone in modern analytical chemistry, integrating both art and science to unravel the complexities of molecular structures. This abstract delves into the fundamental principles that underpin LC-MS, showcasing its multifaceted nature as both a scientific discipline and an art form. The convergence of liquid chromatography and mass spectrometry techniques has revolutionized the field, allowing researchers to achieve unprecedented levels of sensitivity, selectivity, and speed in molecular analysis. The scientific aspect of LC-MS involves the understanding and optimization of chromatographic separations, ionization processes, and mass spectrometric detection. Chromatographic principles, including stationary phase selection and mobile phase composition, play a crucial role in achieving high-resolution separations. Meanwhile, ionization techniques such as electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) contribute to the generation of reliable mass spectra. The interpretation of mass spectra, isotopic patterns, and fragmentation pathways further enhances the analytical capabilities of LC-MS.
