About

Dr. Jan den Hartigh is a leading figure in bioanalytical chemistry, with a specialized focus on the development and validation of advanced chromatographic methods for drug analysis in biological matrices. His work is particularly renowned for advancing the quantification of bisphosphonates—a class of drugs critical for treating bone disorders—by overcoming their notoriously challenging analytical properties. His most-cited study, "Semi-automatic liquid chromatographic analysis of olpadronate in urine and serum using derivatization with (9-fluorenylmethyl)chloroformate" (2000, 19 citations), exemplifies this contribution. In this work, Dr. den Hartigh introduced a robust, semi-automated HPLC method that employed pre-column derivatization to enable sensitive and reliable detection of olpadronate, a feat previously hindered by the compound's lack of chromophores. This methodological innovation not only provided a practical tool for pharmacokinetic studies but also set a benchmark for analyzing other non-UV-absorbing drugs. With a citation record that underscores the enduring utility of his techniques, Dr. den Hartigh's research continues to inform clinical pharmacology and therapeutic drug monitoring, solidifying his reputation as a meticulous innovator in analytical science.
