Application Notes: General

The article describes a comprehensive automated prep purification workflow targeting semaglutide, a GLP-1 receptor agonist, using dedicated method development software to automatically optimize a gradient profile and search for conditions that meet the specified separation criteria. This was followed by scale-up to purification scale and streamlined confirmation of the purities of collected fractions using benchtop MALDI-TOF MS.

This article describes how to efficiently achieve the optimal peak separation for charge variants of a monoclonal antibody using pH gradient ion-exchange chromatography and LabSolutions MD, dedicated software that can automate the entire method development workflow, including the generation of an analysis schedule, mobile phase preparation, and data processing.

This article describes the efficient development of robust analytical methods based on Analytical Quality by Design (AQbD) using dedicated LabSolutions MD software, which supports each phase of the process – screening, optimization, and validation – using functions such as experimental design, building of design space by automatic Peak Tracking, and robustness evaluation.

Per- and Polyfluoroalkyl Substances (PFAS), a family of more than 4,700 chemical molecules, are known for their non-stick and waterproof properties. These versatile compounds find their application in a variety of industries, including cosmetics, textiles, and automobiles. PFAS exhibit remarkable resistance to degradation, which has led to their pervasive distribution in the environment and consequent human exposure. The effects of such exposure are far-reaching, including adverse effects on fertility, developmental abnormalities, cholesterol levels, immune function, and an increased risk of certain cancers. In addition to their toxicological effects, PFAS have become a global concern as regulators and researchers strive to understand the extent of their impact and develop effective methods for detection and mitigation. This collection of articles brings together research on the contamination and effects of PFAS in air, soil, and water, shedding light on the complex challenges posed by these persistent substances in our environment. Overall, this collection of articles seeks to advance researchers' knowledge of the dynamics, effects, and detection of PFAS.

Cells beyond their sell-by date exhibit a higher probability to propagate damaged cellular components like DNA, which leads to disease. It is therefore necessary for the body to remove these old malfunctioning cells, which can be done with garlic. All of the active components of garlic are easily isolated using the 5 µm PRP-C18 HPLC column.

Capsaicin, the compound responsible for the burning sensation in chili peppers, has been researched for its potential therapeutic benefits, including reducing cholesterol and blood sugar levels, and exhibiting anti-inflammatory and analgesic properties. Hamilton's PRP-C18 reversed-phase HPLC column was used to isolate major capsaicinoids, with formic acid as the aqueous mobile phase, achieving good correlation with literature values at 10190 Scoville Heat Units. The Hamilton PRP-C18 column demonstrated excellent peak shape and can be easily regenerated, making it an indispensable tool for synthetic chemists.
