Harald Pasch

About

Harald Pasch is a leading figure in polymer analysis, renowned for pioneering advanced separation and mass spectrometry techniques. His research centers on the hyphenation of liquid chromatography, particularly liquid chromatography at the critical point of adsorption (LCCAP), with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). This powerful coupling allows for the detailed characterization of synthetic polymers, resolving complex mixtures by both functionality and molar mass. In his highly cited 2001 work (122 citations), Pasch demonstrated the efficient analysis of poly(propylene oxide)s using a robotic interface to coaxially add the MALDI matrix to the eluate, enabling precise, dropwise spotting. This innovation provided a robust method for determining end-group distributions and molar masses in polymers like fatty alcohol ethoxylates. His contributions have fundamentally advanced the field of polymer analytics, offering researchers a reliable toolkit for unraveling the structural complexity of industrial polymers. Pasch’s work remains a cornerstone for students and scientists seeking to understand polymer heterogeneity at the molecular level.
