Modernizing, Managing, and Complying to Regulatory Advances in Science
This tutorial covers the strategy and business impacts of transferring liquid chromatography methods to new technologies, between laboratories, and even between companies when necessary. Specifically: what are the ‘rules’ that companies/laboratories must follow, how are they changing, and what does it mean? Waters will demonstrate solutions that have been developed to efficiently transfer methods while maintaining compliance in regulated laboratories. Throughout this presentation we will be using examples from actual situations, and discussing real-world troubleshooting tips to consider when difficulties are encountered. The process required to modernize and manage method transfers is often complex, and may benefit from an on-site consultation by Waters Professional Services in order to provide a tailored solution for your specific quality system.

Intact Protein Analysis of Biopharmaceuticals
K. Cook, J. Bones
Biopharmaceuticals represent over $150 Billion in revenue globally each year and continues to grow. Alongside this there is the requirement for the comprehensive characterisation of biopharmaceuticals during all stages of drug development and manufacture to ensure safety and efficacy. Liquid chromatography with mass spectrometry (LC-MS) allows the characterisation of intact and digested biopharmaceuticals, typically antibodies, to determine glycosylation patterns, charge variants, antibody-drug conjugate ratio determination and more. In the seminar, we will present a comprehensive overview of the latest developments in liquid chromatography separations for the characterization of bio therapeutic proteins, including new chemistries and UHPLC enhancements to provide faster, more reproducible and information-rich workflows. The use of a single UHPLC/ high resolution Orbitrap mass spectrometer platform to measure multiple critical attributes including Glycoforms, PTM’s, intact mass and sequence conformation will also be discussed and demonstrated.
Wide pore monolithic silica of various functionalization: Protein A, C18, C8 and C4, in high performance liquid chromatography for large molecule separations
In the last years the pharmaceutical market has changed dramatically from small molecules to protein-based drugs. The development of biological entities is strong increasing because biotechnological processes now enable a production with reasonable costs. That implies a demand of suitable analytical methods for process monitoring and quality control of biomolecules with therapeutic purposes. Especially the HPLC is the mostly used analysis method. Most important for the HPLC analysis are the properties of the column. For bigger peptides, proteins or antibodies a new type of columns is needed which provide a good permeability, better mass transfer and a better selectivity. In contrast to conventional packed-particle columns, wide pore (300 A) monolithic silica columns are made of a single continuous-bed rod of high purity porous silica that is then bonded with C18, C8, CN, Protein A. Monolithic columns remove backpressure as the primary consideration in method development and give back the flexibility of choices in flow rates for much higher throughput, column lengths for superior resolution, and solvent choices for optimum selectivities that smaller and smaller sized packed-particle columns have slowly taken away over the decades. Because they have no individual particles to shift or break, column performance is very consistent over much longer lifetimes, making them ideal for relatively ”dirty/matrix rich” sample analysis. Their high permeability also makes them very forgiving of shortcuts and timesaving in sample preparation as well as easier to aggressively flush out to reequilibrate. This presentation will guide you through the world of wide pore monolithic silica materials. Benefits will be demonstrated with many application examples including pharmaceutical and bioanalysis separations (proteins, antibodies, etc.), calibration curves, recovery calculations, and method robustness overviews.
Powerful analytical approaches combined: An introduction to TLC-MS
Thin layer chromatography is a classic in analytical chemistry. No other chromatographic method offers the same level of transparency and flexibility in terms of chemistries used, and options to combine solvent systems for separation. In recent years, the separation efficiency of TLC was significantly enhanced by the introduction of smaller particles sizes and thinner layers. Here, we demonstrate how these developments integrate into a mass spectrometry-based workflow that complements current HPLC-MS workflows in drug synthesis or quality control labs.
Is the supercritical fluid extraction/chromatography promising for metabolite identification?
Despite the fact that SFC and SFE are established techniques in analytical chemistry, their use in bioanalysis and particularly in metabolite identification are limited. In here we show some examples regarding the application of SFE-SFC for analysis of spiked biological matrices samples used in metabolism profiling such as, plasma, blood, urine and feces. The easiness of sample preparation and the full automation of sample extraction prior to the separation could possibly give SFE-SFC technology an advantage in the field of metabolite profiling.
What is the advantage of SFC/MS?
SFC/MS has a great potential in high-throughput and simultaneous analysis of a wide variety of compounds and has been widely used in recent years. We will discuss advantages and benefits of SFC/MS in multiresidue analysis through comparison with LC/MS. Moreover, we will also show a basic concept for optimization of the MS parameters in SFC/MS analysis because SFC/MS requires a specific optimization of MS parameters for maximizing sensitivity due to the difference of the mobile phase conditions from those of LC/MS.
Teaching Practical HPLC at a Distance
Teaching practical and analytical techniques to large numbers of science undergraduate students has always been an issue; doubly so, if you are a distance-learning institute. It has always being difficult for students to gain hands-on experience with complex liquid chromatography, despite this experience been needed to support their theoretical studies. The ability to use such equipment is important for graduatesd in the workplace. The Open University is the UK's largest academic institution and a world pioneer in distance learning. To date, the OU has taught over two million students and we are applying this experience in developing online, accessible resources to allow practical studies to be achieved at a distance, through the OpenSTEM Labs. In this talk Dr Turner will present how the Open University, in partnership with Shimadzu, are developing a student friendly, remote access UHPLC platform which will enable us to teach students practical HPLC, from first principles, through to the practice of method development. -- The Open University is incorporated by Royal Charter (RC 000391), an exempt charity in England & Wales and a charity registered in Scotland (SC 038302).

How to manage 10.001 Prep-LC Samples with a small analytical Team? - New Pathways with exceptional Accuracy and Flexibility
Colinda van Tilburg, Mercachem
We share our approach to handle a lot of samples but don’t forget that these samples were made with lots of love and effort. Some chemists made libraries with large number of samples, some make one compound. Both want to get a pure compound back with the highest recovery possible. We have found a workflow to manage this reliable, day after day.

Combining the Powerful Particles with Powerful Selectivities
The modern age of chromatography has seen inventions such as Sub 2 µm materials and Core-Shell particles that provide the scientist with higher resolving power through higher efficiencies. If one, however, looks at the resolution equation, resolution is significantly more dependent on selectivity than on theoretical plates. Therefore, in order to take full advantage of the extra efficiency that the newer generation particle provide, we need modern, improved stationary phase selectivities to work with the high efficiency platforms. In this talk we will show how modern surface chemistry technologies in conjunction with modern UHPLC particle technologies provide significant separation advantages in difficult applications.
Chromatographic Behavior of Biomolecules when using Controlled Surface Charge (U)HPLC Sorbents
Recent developments in (U)HPLC sorbents include materials where the surface charge has been intentionally modified and controlled. The utility of sorbents with a controlled, slightly positive surface charge has been shown to improve the chromatographic performance of basic, small molecules when using common, low ionic strength mobile phases [1,2]. However, the use of these new, controlled surface charge sorbents for the analysis of intact biomolecules has not been significantly explored. In this contribution, the effect of sorbent surface charge on the chromatographic behavior of a variety of biomolecules will be explored. Biomolecule pI and amino acid composition will be carefully chosen to span ranges of practical interest. The interplay between biomolecule properties and sorbent surface charge will be explored.
Sciex Lunchtime Vendor Seminar
Gavin Fisher, Sr. Director Liquid Chromatography (LC) Business, Sciex
Erika Lin, Product Manager - Micro Nano LC, Sciex
Steve Lock, Market Development Manager, Sciex
Scientists working with Electrospray- Mass Spectrometry (ESI-MS) must choose the best separation technique and flow regime for their application. This choice is driven by many factors including analyte type, Limits of detections, sample matrix and quantity of sample. In this workshop, we will take the example of peptide quantitation to discuss two alternatives to traditional analytical flow ESI-MS for peptide quantitation: micro-flow LC-MS and CESI-MS.
When the sample quantity is limited and extra sensitivity is needed, micro-flow LC-MS can increase sensitivity by up to 5 x, compared to analytical flow LC-MS. This approach provides accurate and reproducible results for applications such as peptide quantitation and is ideal for high throughput trap-elute workflows. The sample is loaded at a high flow onto a trap column and then back flushed through a LC column at micro flow rates to the MS detector. The result is up to a 5x shorter run time compared with direct injection micro flow LC-MS.
For charged and polar analytes in minute sample volumes, intact proteins and challenging peptides CESI-MS can be the right choice. For example, highly basic peptides are difficult to analyze by LC/MS methods as they bind to columns and LC systems and have very poor chromatographic properties. We will describe the development of a CESI-MS method for the analysis of highly basic neuropeptides at physiological levels in biological fluids, not possible with LC/MS.
Innovation in Enantiomeric Separations and Related Fields
Over the last four decades there has been a significant growth in the acceptance and implementation of enantiomer separations in the life science industries. DAICEL has been the principal company in this area by developing new innovative products and supporting new users with local technical support. The list of recent new product introductions and supporting activities include commercial introduction of Immobilized polysaccharide-derived Chiral Stationary phases (CSPs) in 2004, the development of innovative screening strategies and as a result, the launch of more than 750 products are some of the achievements in the quest for solutions to customer needs. This continual innovation is inspired by the unmet needs of the scientific community. In the last 12 months this has included the design of new chiral selectors with complementary and enhanced selectivities (CHIRALPAK IG and IB-N); the search for faster and more efficient resolutions (sub 2 µm based CSPs) and extending our experience into the quest for enhanced selectivities in achiral separations (DCPack SFC A and SFC B). This presentation will review the major historical innovations, the recently introduced products and the future activities of Daicel and Chiral Technologies.

Enhancements for Improved Routine Impurity Analysis
The presence of a known impurity or an unknown contaminant, even at trace levels, can have serious consequences for the safety or quality of a product or the environment, be that a pharmaceutical, food and beverage or a water/soil sample. Especially within routine and manufacturing supporting laboratories, false positives or false negatives can have significant quality impacts as well as financial consequences (i.e. loss of production batch). A range of examples will be presented, which not only provides increased quality of the assay results itself, but also employs state-of-the art trouble shooting strategies and multi-detection concepts. This seminar will showcase our comprehensive new workflow solution for impurity analysis with a focus on pharmaceutical impurities as well as environmental testing and how quality can be assured at each stage of the workflow. We shall reveal new technology to bring mass spectrometry to chromatographers and how the Thermo Scientific™ Chromeleon™ CDS software can be used for both HPLC and IC separations and mass spectrometry, whilst ensuring data integrity and reproducible performance. Furthermore, we shall offer alternative liquid chromatography detection methodologies for difficult to detect compounds using charged aerosol detection and suppressed conductivity detection.
