HPLC High-performance liquid chromatography is a chromatographic technique widely used for separation, identification, and quantitation of components in complex mixtures. It underpins workflows in Pfizer, Merck & Co., GSK, Johnson & Johnson, and research at institutions such as Massachusetts Institute of Technology, University of Cambridge, Stanford University, and Max Planck Society laboratories. HPLC development involved contributors associated with Imperial Chemical Industries, GlaxoSmithKline, Eli Lilly and Company, and national laboratories including Lawrence Berkeley National Laboratory.

Introduction

HPLC emerged from foundational work linked to Nobel Prize in Chemistry recipients like Archer Martin and Richard Synge and from instrumental advances spurred at industrial centers such as DuPont and academic groups at University of California, Berkeley. Early commercial systems were produced by companies like Waters Corporation, Shimadzu Corporation, and Agilent Technologies. The technique integrates engineering from firms such as Beckman Coulter and Thermo Fisher Scientific and finds regulatory use in agencies including European Medicines Agency and United States Pharmacopeia.

Principles and Instrumentation

The core principle relies on differential partitioning between a mobile phase and a stationary phase, a concept refined by researchers at Royal Society of Chemistry meetings and presented in conferences hosted by American Chemical Society and Society for Applied Spectroscopy. Typical instrument components—pump, injector, column, detector, data system—are supplied by vendors such as PerkinElmer, Bio-Rad Laboratories, and Agilent Technologies. Columns house packing derived from manufacturers like Kromasil and materials developed by groups at University of Illinois Urbana-Champaign and Tokyo Institute of Technology. Detectors include ultraviolet-visible devices influenced by designs at General Electric laboratories and mass spectrometers from Bruker and Sciex; coupling to Orbitrap and Quadrupole analyzers facilitates work at centers like Lawrence Livermore National Laboratory and Rutherford Appleton Laboratory.

Modes and Variants

Variants include analytical, preparative, and ultra-high-performance liquid chromatography, with UHPLC pioneered by teams at University of Geneva and ETH Zurich. Separation modes—reverse-phase, normal-phase, ion-exchange, size-exclusion, chiral—are standardized in methods referenced by Pharmacopeia Commission bodies and used in industrial settings at Novartis and Sanofi. Specialized formats such as hydrophilic interaction chromatography (HILIC) and affinity chromatography are applied in proteomics labs at Cold Spring Harbor Laboratory and Scripps Research. Supercritical fluid chromatography developments involved collaborations with CERN and aerospace research at NASA.

Method Development and Validation

Method development integrates chemometrics taught at Massachusetts Institute of Technology and Imperial College London and leverages software from Waters Corporation and Agilent Technologies. Validation follows guidelines from International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use and standards set by ISO committees and United States Food and Drug Administration. Robust methods are used in clinical diagnostics at Mayo Clinic and Cleveland Clinic, and in forensic laboratories linked to FBI crime labs. Statistical approaches include design of experiments employed by engineering departments at Princeton University and University of Michigan.

Applications

HPLC supports drug development pipelines at AstraZeneca and Bayer AG, environmental monitoring by United States Environmental Protection Agency and Environment Agency (England), and food safety testing under Food Standards Agency (UK) mandates. In clinical settings, laboratories at Johns Hopkins Hospital and Karolinska Institutet use HPLC for therapeutic drug monitoring. Proteomics and metabolomics applications are central to projects at Wellcome Trust and Human Genome Project-related consortia. It is employed in quality control at Heineken and Nestlé, in forensic toxicology used by Interpol cooperating labs, and in academic research at Yale University, University of Tokyo, and University of Oxford.

Advantages and Limitations

Advantages cited by industry and academia include high resolution demonstrated in studies from Stanford University, speed improvements achieved with UHPLC at ETH Zurich, and quantitative reliability required by European Directorate for the Quality of Medicines and United States Pharmacopeia. Limitations involve solvent consumption addressed by green chemistry initiatives at University of California, Berkeley and detection limits sometimes requiring hyphenation with mass spectrometry platforms from Bruker and Thermo Fisher Scientific. Cost considerations are managed by procurement teams at National Institutes of Health and centralized labs in university hospitals like Mount Sinai Hospital.

Safety and Maintenance

Safe operation follows guidelines from occupational health units at Centers for Disease Control and Prevention and Occupational Safety and Health Administration. Routine maintenance procedures are taught in training programs by Waters Corporation and Agilent Technologies and implemented in core labs at European Molecular Biology Laboratory and National Center for Biotechnology Information. Waste handling protocols align with regulations from Environmental Protection Agency and local authorities, and instrument service contracts are commonly held with manufacturers such as Shimadzu Corporation and PerkinElmer.
