Tuesday, November 15th 2022 Morning Session: 11am EST|8am PST|4pm GMT|5pm CET Afternoon Session: 2pm EST|11am PST|7pm GMT|8pm CET Analyzing oligos? Join us to learn about novel, automated, and integrated software to support the analysis of the CQAs of oligos using LC–HRAM MS. Purity and sequencing data will be presented for a multitude of oligos including antisense, aptamer, and long synthetic samples.

Airing 1: Thursday November 10, 2022 at 9am EST Airing 2: Thursday November 10, 2022 at 2pm EST Polymer characterization is key to understanding their properties and ensuring the quality of final products containing polymers. Discover why light scattering and viscometry in size-exclusion chromatography become the new gold standard in polymer analysis.

Pepsin digestion and guanidine hydrochloride post-digestion can improve sequence coverage in antibody peptide mapping compared with trypsin digestion.

A critical step in any troubleshooting exercise—but one that I think is underappreciated—is recognizing that there is a problem to be solved.

Are generic workflows really needed in environmental analysis? In the end, it is the analyst— not instrumentation or software—that is in charge of what data are obtained, after thoughtfully considering what sample preparation and acquisition method to use.

This method greatly facilitates the analysis of a large number of pesticides.

We continue our “Critical Evaluation” series with a consideration of liquid chromatography (LC) methods that use mass spectrometric detection.

Better sample preparation and miniaturized separations are enhancing these analyses.

Sample preparation and analysis of pharmaceuticals in wastewater present unique challenges. Here, we describe those challenges.

With a new prototype, we explore how to improve the resolution power and usability of LC–MS instruments for routine analysis in pharmaceutical applications.

Although well known, the extent of adduct ion formation in LC–ESI-MS/MS, and the implications for quantitative analysis and analyte characterization are not fully appreciated. We explore this problem and explain the implications for reproducibility, quantitative and qualitative analyses, and DDA and DIA.

With the advent of ambient ionization and portable mass spectrometers, the ability to perform rapid, on-site analysis is fast becoming a reality. We review the critical recent developments enabling this capability as well as remaining challenges that must be tackled to enable widespread adoption.

Advances in sample preparation have enabled analysis of RNA modifications in single cells, paving the way to discovering new insights into the functions of these molecules.

The benefits of tandem LC–MS are revealed.
