Mastering Tricks for Improving Chromatography in Difficult Samples
Ion chromatography, a crucial method for separating and quantifying ionic components, faces complexities in diverse sample matrices. To meet stringent analysis standards and ensure IC component longevity, sample pretreatment is essential. Samples with elevated particulate loads, extreme pH, colloids or high cation concentrations jeopardize chromatographic integrity, potentially reducing column lifespan. Considerations extend to IC-incompatible matrices, like those involving organic solvents, and scenarios requiring ultra trace analyses with preconcentration.
While manual methods exist, the revolutionary shift to inline automation for sample preparation promises increased efficiency, throughput, prolonged column lifespan and notable enhancements in data accuracy and reproducibility.

Mastering UPW Quality with Real-Time Trace Ion Detection
Ultrapure water (UPW) is crucial for the production of superior-quality semiconductors, but ensuring final product quality can be a challenge without the right tools. UPW undergoes extensive and costly purification, utilizing various physical and chemical treatments to meet increasingly rigorous purity standards. In the face of global water shortages, efficient UPW production is essential. Water recycling facilities at semiconductor plants are tasked with addressing this concern, regenerating wastewater back into UPW. However, the integrity of regenerated UPW must be verified to ensure final product quality. This is where online ion chromatography provides a novel advantage: detecting trace anions, cations, and silica contaminants in real-time down to parts-per-trillion levels.
Join us for a conversation with two industry experts: Ben Greenwood, Senior Manager at Micron Technology's Chemistry Lab, and Dariana Martinez, Product Application Specialist at Metrohm USA. Together, they will delve into the pressing water challenges currently faced by the semiconductor industry. Additionally, they will shed light on the pivotal role of ultrapure water and the significance of real-time ion chromatography to ensure quality control.

Direct Analysis of Glycosylated Therapeutics
Glycosylation plays a crucial role in determining the pharmacological properties of biotherapeutics. The molecular heterogeneity of glycosylated biotherapeutics makes it difficult to provide thorough characterization of intact glycoproteins by mass spectrometry. Current methods for analyzing biotherapeutics only measure fragments of the compound or rely on partial digestion of the glycans to reduce sample complexity. These limitations pose important risks and challenges for biotechnology companies that need to report human-compatible and consistent glycosylation, critical for drug safety and efficacy.
We will present a new approach to glycoform fingerprinting that uses proton-transfer charge-reduction with gas-phase fractionation to analyze intact glycoproteins by mass spectrometry. The method provides a detailed landscape of the intact molecular weights present in biotherapeutic protein preparations in a single experiment and offers insights into glycoform composition when coupled with a suitable bioinformatic strategy. In addition, we highlight the application of charge detection native mass spectrometry (Direct Mass Technology mode) towards the elucidation of masses and aggregation of heterogeneous glycosylated biotherapeutics.

The Predict-First Paradigm: How Digital Chemistry is Changing Drug Discovery
Drug discovery chemists often ask two common questions: “What is the most efficient way to test my hypothesis?” and “How can I iterate on my ideas quickly?”
Digital chemistry offers a modern paradigm for answering these questions by enabling rapid in silico testing of design ideas using highly accurate digital assays of key properties, accessible across whole project teams. This shift from design strategies based largely on experimental trial and error towards a ‘predict-first’ approach to drug discovery allows teams to dramatically expand the pool of molecules that can be explored and results in a highly interactive and fully in silico design-make-test-analyze (DMTA) cycle. Chemists are empowered to test hypotheses through predictive modeling and iteratively improve designs prior to compound synthesis. Teams can confidently spend time and energy exploring new, unknown, and often more complex designs while sending only the top performing molecules for synthesis.
In this webinar, we will walk through the digital chemistry strategy used by Schrödinger’s Therapeutics Group, which has led to several successful clinical-stage drug candidates. We will demonstrate how this strategy is based in LiveDesign, Schrödinger’s cloud-native, collaborative enterprise informatics platform, which empowers teams to design, computationally assess, and prioritize new compounds together in real-time.
