About

J. Hempenius is a pioneering analytical chemist whose career has been defined by a relentless pursuit of automation and efficiency in bioanalytical method development. Working primarily at the intersection of pharmaceutical analysis and laboratory technology, Hempenius made significant contributions to the automation of drug quantification in human plasma — a critical challenge in clinical pharmacology and drug development. Among his most influential achievements is his early foundational work on laboratory robotics, beginning in 1990 with a landmark two-part series exploring automated bioanalytical systems, including innovative computer-guided safeguarding protocols. This groundbreaking work laid the groundwork for his later research into high-throughput solid-phase extraction (SPE) technologies, which dramatically accelerated the analysis of clinically important drugs such as cimetidine, haloperidol, felbamate, and theophylline. His 1999 paper combining high-throughput SPE with turbo ionspray LC-MS-MS represents a notable methodological advance, garnering 44 citations and reflecting the field's growing embrace of hyphenated mass spectrometric techniques. Hempenius also explored the integration of robotics with chemometrics to optimize drug extraction procedures, underscoring his interdisciplinary vision. Collectively, his work has shaped modern bioanalytical laboratory practice, streamlining workflows that underpin drug safety and efficacy testing worldwide.
