Native mass spectrometry (nMS), in which intact protein or nucleoprotein complexes are directly measured, commonly involves exchange of nonvolatile electrolytes (NaCl, PBS, Tris) for volatile electrolytes such as ammonium acetate. This can be time-consuming if offline buffer exchange spin cartridges are used. Furthermore, some samples may not be stable if left in nonvolatile buffer for more than just a very short period of time. This problem can be avoided if an LC-compatible online buffer exchange column is used to separate protein complex from salt. In this experiment, no attempt is made to perform size exclusion chromatography to separate protein complexes of different sizes but rather any protein complex that is injected onto the system is simply separated from low mass salts that would otherwise product heavily adducted protein complexes that appear as broad peaks in the mass spectrum. This webinar will focus on the development of online buffer exchange (OBE) for nMS applications and will describe how the experiment is implemented and how it can be extended by coupling to affinity separation (e.g., IMAC-OBE) to be used to optimize protein overexpression. Key Learning Objectives: The use of online buffer exchange for high throughput native mass spectrometry Online buffer exchange nMS allows to directly screen structural features of large biomolecules even if such biomolecules are not very stable in MS friendly buffers How the coupling of affinity separation (e.g., IMAC-OBE) to online-buffer exchange can be used to optimize protein overexpression Who Should Attend: MS practitioners Researchers/ R&D Managers Laboratory Managers/ Directors / Supervisors Laboratory Technicians / Operators Structural Biologists Scientists in biopharma engaged in biotherapeutic characterization Brought to you by: Vicki Wysocki, Ph.D. Professor, Dept of Chemistry and Biochemistry The Ohio State University Catherine Dold Health & Environment Writer, C&EN Media Group

Catalysts facilitate the creation of almost all synthetic materials we interact with everyday. New materials require new catalysts with enhanced and novel properties. Traditional synthetic approaches for materials discovery are expensive and slow. First-principles simulation has become a reliable tool for the prediction of structures, chemical mechanisms, and reaction energetics for the fundamental steps in homogeneous catalysis. Details of reaction coordinates for competing pathways can provide the fundamental understanding of observed catalytic activity, selectivity, and specificity. Such predictive capability raises the possibility for computational discovery and design of new catalysts with enhanced properties. Unfortunately, this is an arduous process that requires meticulous maintenance, specialized training, and accounting of hundreds of files and properties. To facilitate the fundamental understanding, design, and discovery of novel catalysts, an automated enterprise solution was designed and developed for collaboration between synthetic and computational chemists on a single web-based platform. Key Learning Objectives: Discover the predictive capabilities of physics-based modeling in reactivity and catalysis. See how automated high-throughput screening accelerates synthetic discovery. Learn how a web-based platform can generate more ideas and drive innovation through the collaboration of computational and synthetic chemists.

The characterization of extractables and leachables (E&L) is an integral part of ensuring biocompatibility for many medical devices and pharmaceutical products. Guidance for E&L has been provided in USP <1663> and <1664> for pharmaceutical products and in ISO 10993-18 for medical devices. The first step in the E&L process involves detection of those compounds which are suspected to be at or above the level of toxicological concern. This process is accomplished through the use of the Analytical Evaluation Threshold (AET) which links the toxicologically relevant concentration to the observed analytical signals. A significant problem in AET evaluation is caused by response factor (RF) variation. It is an unfortunate reality that compounds which are at equivalent concentration do not always or even often give equivalent signal response on various detector systems including mass spectrometers. Recent publications have highlighted these risks for both LCMS (Jordi, et al. J. Pharm. Biomed. **bleep**. 2018, 150, 368–376) and GCMS (Jenke and Odufu, Journal of Chromatographic Science 2012;50:206–212). The prominent and necessary use of surrogate standards for AET evaluation introduces error into the precise estimation of the signal strength which corresponds to the toxicologically relevant concentration. To overcome this problem, an uncertainty factor has been introduced into the AET equation and regulatory agencies have provided recommendations as to values for the UF (GC/MS with UF =4, LC/MS with UF =10). While this approach does account for response variation, it also introduces other difficulties including lower AET values which can be difficult or impractical to achieve which then require additional sample concentration due to limited instrument sensitivity. This has the potential to counteract the perceived benefit resulting in compound loss or degradation and additional regulatory scrutiny of the sample preparation process. This approach also results in a significant potential for false positives (I.e., compounds that are below the AET concentration are determined to have a peak area above the threshold associated with the AET). An alternative approach is therefore desirable. In this webinar, a new case study will be presented using the multidetector approach to AET evaluation contrasted with the use of the recommended UF of 4 and 10 for a model polymer system. The multidetector approach leverages the independence of the response factors for a given compound obtained on different detectors and chromatographic systems to overcome potential weak signals on any one detector and thus reduces the reliance of the method on UF to overcome response variation. The multidetector approach was summarized in two recent publications (Jordi, et al. J. Pharm. Biomed. **bleep**. 2020, 186, 1-14 and Jordi, et al. PDA Journal, vol. 75, No. 2 2021, pg. 289-301). The effectiveness of using a combination of triple detection Liquid Chromatography Mass Spectrometry (LCMS) with Ultraviolet (UV) and Charged aerosol detection (CAD) as well as Gas Chromatography Mass Spectrometry (GCMS) will be presented. Quantitation for a series of reference compounds characteristic of the polymer systems will be used to gauge the potential for false positives using the different AET approaches. Finally, the benefits of this approach for detection of compounds with little to no mass spectrometry response will be highlighted. Key Learning Objectives: Objective 1: What is the Analytical Evaluation Threshold and how should it be applied? Objective 2: Review a Case study comparing the use of regulatory agency recommended approaches to AET evaluation and a multidetector approach. Objective 3: How can using a multidetector approach reduce the need for large UF and by extension the need for additional sample preparation steps?

There is a trend in the materials industry towards thinner and thinner coatings that create new applications and enable both material and cost savings. However, as coatings become thinner, the traditional methods for coating hardness testing become less accurate or fail entirely. Although methods are available for measuring the hardness of thin films, up until now, they have tended to be both price-prohibitive and require extremely complex and difficult to use instrumentation. With the introduction of the Hit 300, accurate hardness testing of thin films is now both accessible and affordable for any lab or production site developing new coating materials. Anton Paar is proud to present “Accessible and Affordable Hardness Testing of Thin Coatings,” a live webinar discussing the benefits and limitations of traditional hardness testing as well as new developments that enable accurate and affordable hardness measurements of ultrathin coatings.

Multidimensional measurements integrating liquid chromatography, ion mobility spectrometry and mass spectrometry (LC-IMS-MS) provide valuable polarity, structural and mass information simultaneously for lipidomic analyses and show tremendous power for attaining more confident lipid identifications. For all of their advantages, LC-IMS-MS measurements are highly complex and result in huge datasets which are difficult to process in a timely fashion. Thus, developing a data analysis workflow that is capable of accurate and rapid molecular analyses is essential. The freely available, open-source software Skyline offers targeted processing of lipid data which ultimately allows for confident identification of diverse lipid species. We have developed sample-specific lipid spectral libraries which include over 700 target lipids from multiple lipid categories. Each target lipid is populated with m/z values, normalized retention times, ion mobility collision cross section (CCS) values, and known fragmentation patterns. These values were manually extracted from LC-IMS-MS experimental data and verified using existing literature. Recently developed aspects of the Skyline small molecule interface are utilized in this workflow including IMS spectrum filtering and retention time prediction (iRT) using a set of ~20 endogenous lipids for gradient correction and LC alignment. Application of lipid CCS value filtering further increased lipid annotation confidence and greatly improved the signal to noise ratio for the target species. These lipid spectral libraries have undergone additional validation studies and have recently been made publicly available through Skyline’s online repository Panorama. In comparison to previous studies of NIST SRM 1950, this workflow when coupled with an LCIMS-CID-MS platform gave hundreds of confident annotations using a single sample extraction and analysis platform. Key Learning Objectives: Learn to overcome challenges with large, highly complex datasets generated from liquid chromatography, ion mobility spectrometry and mass spectrometry lipidomic analyses. Developing sample-specific multidimensional lipid libraries using Skyline. Build a workflow leveraging Skyline automation features such as small-molecule spectral libraries, drift time filtering, iRT retention time prediction, analysis of multiple adducts, and neutral loss fragments.
