Course Descriptions

SHORT COURSE #1 (Full day Saturday 9:00am-4:00pm)

Two-dimensional Liquid Chromatography: Principles, Instrumentation, Method Development, and Applications

Instructiors: Dwight R. Stoll, Gustavus Adolphus College and Mark R. Schure, Kroungold Analytical, Inc.

In 2DLC, sample components are fractionated by two different columns utilizing different retention mechanisms. To achieve successful 2D resolution of complex sample components, dissimilar (orthogonal) retention mechanisms are required to effectively spread the peaks throughout the available separation space. In this course we will discuss in detail: • Theory of 2DLC, from a practical point of view • Instrumentation, including commercially available instruments • Method development across a wide variety of sample types • Applications to lipids, peptides, proteins, small and large molecule pharmaceuticals, biological extracts, industrial polymers, and surfactants • Helpful insights that are important for achieving good results in the lab Students are expected to be familiar with HPLC. Those who take this course will learn background information essential to understanding the technique and achieve practically useful results with commercial instrumentation. Many aspects of 2DLC are shared with one-dimensional HPLC such as column technologies, pumps, solvent systems, and matching the detector. However, 2DLC has some issues which are not present in one-dimensional HPLC, and these will be explained in detail so that course participants will have this knowledge prior to starting method development. We will also explore the suitable instrumentation for 2DLC, and how to process data external to the acquisition software. Applications of comprehensive 2DLC will be shown for complex industrial and biological samples, as well as simpler applications such as column switching, target peak purity investigation, and biopolymer analysis using commercial two-dimensional chromatographic instruments.

Field-Flow Fractionation (FFF): Polymer and Colloid Characterization

Instructor: Jeffrey A. Ahlgren, Senior Applications Scientist, Western Region, Wyatt Technology Corporation

One of the primary challenges for reliable and accurate characterization of biotherapeutics, nanoparticles, polymers, and proteins is effective analytical separation and detection. This is especially true for inherently polydisperse complexes, and those with aggregates or branched constituents. This workshop will explore the history, development and principles of operation, and latest advances in the area of flow Field-Flow Fractionation (FFF), coupled with multi-angle light scattering (MALS) to demonstrate how FFF — in a single-fluid pathway—enables highly tunable separations and robust sample characterization, while overcoming the inherent limitations of other techniques. The case studies presented will illustrate a broad suite of measurements afforded by FFF-MALS, including multi-detector analysis, molar mass determinations and high-resolution size distributions from 1–1000 nm, as well as quantitative particle concentration determination.  Learn how these techniques are applied to a variety of biotherapeutics and functionally relevant polymers, proteins, and complexes. New capabilities presented will include sensitivity enhancements resulting from sample dilution control and advances in in-silico method development to shorten method development time.

SHORT COURSE #8 (Half-day Sunday 9:00am-12:00pm)

Chiral Liquid Chromatography

Instructor: Prof. Bezhan Chankvetadze, Tbilisi State University

In this course, after a short introduction to the basics of stereochemistry, the analytical and preparative scale separation of enantiomers and the currently available technologies for achieving this goal will be reviewed. After comparing different synthetic and separation strategies, the latter will be discussed in more detail with emphases on liquid phase techniques, such as high-performance liquid chromatography (HPLC) and super-/sub-critical fluid chromatography (SFC). All currently available modalities of liquid-phase separation techniques for analytical and preparative scale separation of enantiomers will be reviewed with focus on various chiral selectors and stationary phases and their performance from the viewpoint of analyte coverage, applicability in various separation mode(s) and their suitability for analytical and preparative purposes, respectively. The most widely used chiral selectors will be discussed, such as polysaccharide derivatives, along with the strategy of developing and selecting a promising CS, in combination with the optimal silica support.  Modalities of attachment of a chiral selector to the silica surface will be also discussed. CSP preparation will be linked to the chromatographic performance of these materials. Significant attention will be paid to analytical and preparative method development with polysaccharide-based CSPs, enantiomer elution order, kinetics and thermodynamics of separation.  Unusual observations will be discussed along with their significance for analytical and preparative-scale method development. Current trends in the field of enantioseparations, such as ultrafast separations, separation of chiral molecules with multiple chiral centers, etc. will be also reviewed [1]. Reference: [1] B.

Capillary Electrophoresis with Mass Spectrometry Detection, More than just a Complementary Tool for LC-MS

Instructor: David D. Y. Chen, Department of Chemistry, University of British Columbia, Vancouver, BC, Canada

LC-MS is currently the most important analytical techniques for many applications in biomedical research and pharmaceutical industry. CE-MS, on the other hand, hasn’t seemed to live up to its potential and has only been successfully used by a relatively small number of scientists.  The reality though, is not always as it seems.  CE technology has quietly been used in the application processes of the majority of the new drugs approved by the US FDA in recent years.  With the improvement in the interface technology between CE and MS, the sensitivity and robustness of have been significantly improved, and CE-MS technology is poised to become an increasingly more important tool to be used to push the frontiers of biomedical and pharmaceutical research.  The application of CE-MS, including capillary isoelectric focusing directly coupled to mass spectrometry (cIEF-MS) for the analysis of monoclonal antibodies, peptides, and small molecules will be discussed.  New development in protein conformer analysis, characterization of in-solution protein structural differences, protein aggregation, and proton activity analysis by hydrogen-deuterium exchange analysis in conjunction with CE based separation, will also be demonstrated.
