An all-inclusive one-day course on HPLC and UHPLC fundamentals, including theory, column, instrument, and pharmaceutical applications.
This intermediate one-day workshop will provide the analytical scientist with a clearer understanding and solid working knowledge of the concepts, instrumentation, and columns of HPLC and UHPLC (ultra-high-pressure liquid chromatograph). The focus is on pharmaceutical analysis of small molecule drugs.
Key topics include:
Recommended textbook: M. W. Dong, HPLC and UHPLC for Practicing Scientists, 2nd Ed., Wiley, Hoboken, NJ, 2019
Analysts, scientists, researchers, and managers in pharmaceutical and other industries who want to get an updated overview of the fundamentals of HPLC and UHPLC in pharmaceutical analysis and other applications.
A basic understanding of chemistry and HPLC with some hands-on experience is assumed.
1. Modern Concepts
A. Introduction: The chromatographic process, advantages and limitations, and chromatographic modes (NPC, RPC, IEC, SEC)
B. Concepts: Retention factor (k), separation factor (a), column efficiency (N), resolution (Rs), tailing factor (Tf), the resolution equation, the linear solvent strength theory, and column void volume (VM)
Mobile phase factors (organic modifiers, pH, buffers), mass spec compatibility, isocratic and gradient separations, operating parameters (Flow, gradient time (tG), column temperature (T)), peak capacity (Pc), references
2. HPLC Columns, Trends and Selection Guides
A. Column fundamentals: Glossary and abbreviations, Characteristics and types, packing characteristics (support type, particle size, pore size), bonded phases, end-fittings, plate height (H), the van Deemter equation, and estimation of column efficiency
B. Trends: Trends of shorter and smaller columns and the use of high-purity silica, traditional and novel bonding chemistries, the concept of “orthogonality,” a listing of common RPC columns, column selection guide
C. Newer column types: Hybrids, charged surface hybrids, HILIC, sub-3 and sub-2mm, and superficially porous particles (SPP)
3. HPLC instrumentation and Operating Principles
A. System, Pump, and Autosampler. Integrated vs. modular system, solvent delivery system, low-pressure vs. high-pressure mixing, dwell volume and ramification, pump trends, manual injection valve, autosampler types and trends
B. Detectors: Operating principles of UV/Vis detection and characteristics, monitoring wavelength selection, photodiode array detector (DAD), newer detectors for non-chromophoric analytes (ELSD, CAD, and CLND)
C. MS, CDS, peak integration strategy, and Instrument Bandwidth. The mass spectrometer (MS), types and ESI interface, Data Chromatography System (CDS), the concept of instrumental bandwidth (extra-column band broadening), loss of column efficiency vs. column size
4. Drug Development Process, Regulations, and Pharmaceutical Analysis of Small Molecule Drugs
A brief overview of pharmaceutical discovery/development, Chemistry, Manufacturing and Control (CMC), analytical development and quality control in small molecule drugs development, Regulations, potency assay, stability-indicating method, stability study, dissolution testing, chiral separations, and certificates of analysis of drug substance and reference materials, OTC products with multiple actives, herbal products, pharmaceutical counterions and excipients
