Your Autosampler Can Make Mixtures and Calibration Standards
Merlin K. L. Bicking, PhD, President and Senior Analytical Scientist, ACCTA, Inc.
We have automated or improved nearly every step in most chromatography methods, except for the preparation of calibration standards. High precision and accuracy methods still require Class A pipets and volumetric flasks, and large volumes of high purity solvents. This presentation will describe a simple procedure that uses a typical HPLC autosampler to prepare single or as multi-component mixtures of calibration standards at multiple levels. The method is most efficient when you have the ability to program the autosampler directly, but there are simple variations that can be developed without such programming. Multiple applications will be shown that demonstrate the ability to prepare standards that match manual preparations. This on-demand procedure has been successfully validated for GMP use and is an excellent alternative for high-cost standards.
Dr. Bicking has extensive analytical chemistry experience in academia, contract research, independent testing laboratories, consulting, and technical training. His professional history includes development of two EPA methods, as well as numerous methods in other regulated and non-regulated industries. His publications and presentations cover a wide range of topics, including liquid chromatography theory, derivatization, method optimization, and the use of experimental design strategies in analytical chemistry. He also develops and presents technical training seminars for analytical laboratory staff. He has been teaching the CCDG LC School for the last four years.

HPLC-UV Method Development for Baseline Resolution of 17 Cannabinoids
With ongoing discussions regarding the legalization of marijuana along with great interest in the potential medical benefits of hemp-derived products, there is increasing demand upon the cannabis testing industry for analytical determination of cannabinoid content. Current regulations concerning potency vary by jurisdiction, but usually require testing for the active forms of THC and CBD. In addition to those, California requires testing for the acid forms, THCA and CBDA, along with CBG and CBN. As regulations evolve, and as research interests in minor cannabinoids expand, it is important to have robust analytical methods in place that are capable of meeting needs. Herein, the baseline resolution of 17 cannabinoids by high performance liquid chromatography (HPLC) with UV detection is described. Chromatographic method development was performed with particular attention to speed of analysis and means of affecting selectivity for the improved resolution of critical pairs.
Sample Loadability on Coated and Immobilized Polysaccharide-Based CSPs
Chiral stationary phases (CSPs) prepared by coating phenylcarbamate derivatives of amylose and cellulose on supporting silica gels have proven invaluable for the separation and purification of enantiomers in both high-performance liquid chromatography (HPLC) and supercritical fluid chromatography (SFC). One notable limitation of coated polysaccharide phases is the restricted use of certain organic mobile phases, such as acetone, chloroform, ethyl acetate, tetrahydrofuran (THF), and toluene. These solvents must be avoided as they can swell or dissolve the polysaccharide and destroy columns packed with coated CSPs. Immobilized versions of the same chiral selectors have expanded the capabilities of these phases to allow for the use of such solvents in analysis and sample purification. For some applications, however, practitioners have observed important differences in selectivity and sample loading capacities between the coated and immobilized versions. Herein, three examples of chiral separations performed using HPLC and SFC are discussed with respect to how these differences may be manifested and overcome or exploited to advantage.
Edward G. Franklin, PhD, Technical Director of Chromatography Applications at Regis Technologies, Inc. Dr. Edward G. Franklin earned a B.S. in Biochemistry in 2006 and M.S. in Forensic Science in 2007 from Duquesne University in Pittsburgh, PA. In 2012, he received a PhD in Analytical Chemistry from The University of North Carolina at Chapel Hill under the direction of Dr. James Jorgenson. In over 10 years of HPLC-related experience, he has conducted research ranging from fundamental investigations of the kinetic performance of packed-bed HPLC columns, instrument and column development for ultra-high pressure separations of complex samples, and column stationary phase development for application-specific methods. In his current position as the Technical Director of Chromatography Applications at Regis Technologies, Inc., he develops new products and methods for chromatography solutions related to chiral and achiral separations using reversed-phase, normal phase, and supercritical fluid approaches.

Automation: The next critical tool for scientists’ survival during the pandemic and during recovery.
Fred Foster, GERSTEL, Inc. Baltimore, MD
The pandemic forced everyone to learn how to continue to be productive while existing in a remote environment. As scientists, we were able to quickly adapt to virtual meetings, web conferences, and online connections, however, our workloads and the samples needing analyzed did not stop. There is still laboratory work to perform that is harder to complete remotely. When the vaccines are available to all, everyone has been vaccinated, and the ever-present “curve” has finally been flattened, the brick-and-mortar work environment will open again. Once that occurs, all the work that was delayed because of shutdowns, partial work weeks, and working from home will be waiting for all of us. We will need a way to do a lot more with less resources. That is why automating as much as possible will be critical.
This seminar, given in the first month of what will hopefully be the year in which we see the light at the end of the tunnel, will discuss how GERSTEL helps its customers automate their sample preparation and sample introduction methods in order increase throughput, get through the backlog of samples, and ultimately free up resources when they are needed most. The MPS roboticPRO is a highly efficient LC or GC autosampler with extended robotic functionality. It provides reliable processing of complex tasks including automation of liquid-liquid and solid phase extraction procedures and as well as other liquid handling methods. Syringe holders and syringes are integrated in special syringe modules, which can be exchanged automatically within a running sequence when using the MPS roboticPRO for maximum flexibility. The entire system is controlled using the proven GERSTEL MAESTRO software in a simple and efficient manner. Examples of some of the automated sample preparation options and how they are used to provide increased productivity will be highlighted.

The introduction of commercially available UHPLC systems in 2004 and the rapid adoption of its methodology and instrumentation fundamentally altered the landscape of the separations laboratory. While the rules that govern the practice of UHPLC are no different than those that govern HPLC, a much stricter adherence to those rules is necessary. In addition, the proliferation of mass spectrometers as LC detectors has required analysts to think carefully when transferring optical detector-based methods to LCMS platforms. This presentation will review best practices for UHPLC and UHPLC MS. Specific topics of discussion will include tubing & connections, sample diluents, solvent purity, glassware cleanliness, contaminant ions as well as other tips & tricks to make a day in the lab less stressful.

The primary goal for any analytical testing is to develop practices to ensure safety and quality. Modern regulations emphasize analytical methods capable of separating critical analyte pairs, improved efficiency, symmetric peak and detector specific requirements for identification as well as quantitation. In order to meet separation goals and to exceed regulatory requirements, new and unique chromatography technology and selectivity ties should be considered.
In this seminar, we will explore advances in GC under 3 unique topics: We will start with the advances in Gas Chromatography where we will explore evolution of column technology that helps in development of time and cost efficient methods. In the next session, we will discuss the new and improved Zebron GC phase specifically developed for industry specific applications. In the third session, we will explore accessories that can help extend life time of Gc column & detector
