High-Performance Liquid Chrmoatography (HPLC)
High-performance liquid chromatography (HPLC) separates compounds in solution by pumping samples through a packed column at high pressure, then detecting them by UV-Vis absorbance, fluorescence, or mass spectrometry. As a hard skill it requires selecting the appropriate column chemistry and mobile phase for the target analytes, developing and validating gradient methods, and interpreting peak purity and quantitation results from calibration curves. Battery researchers apply HPLC to identify and quantify electrolyte additive decomposition products, characterize organic species in aged electrolytes, and verify purity of synthesized electrolyte components and binders.
