[Viewer Benefits Available] Explaining Tips for LC in a Short Seminar Do you have concerns such as "I'm unsure about column selection," "I'm struggling to optimize analysis conditions," or "I have challenges analyzing compounds with weak retention" in LC analysis? Waters will hold a seminar titled "Must-Listen! Advanced LC Application Seminar" where you can learn practical LC analysis know-how in just 30 minutes. In this seminar, we will cover useful topics in a total of six sessions, including tips for choosing detectors, how to utilize reverse phase columns, scaling up to preparative LC, approaches for analyzing hydrophilic and highly polar compounds, case studies of low-adsorption HPLC, and improving purity through solid-phase extraction. Each session is scheduled to start at 15:00. Event Themes: • October 6 (Tuesday) - Session 1: Tips for Choosing Detectors • October 13 (Tuesday) - Session 2: Tips for Choosing Columns • October 21 (Wednesday) - Session 3: Tips for Preparative LC • October 27 (Tuesday) - Session 4: Approaches for Analyzing Hydrophilic and Highly Polar Compounds • November 5 (Tuesday) - Session 5: Case Studies of Low-Adsorption HPLC • November 10 (Tuesday) - Session 6: Tips for Solid-Phase Extraction

In this seminar, we will introduce case studies of analytical method development using QbD software: Fusion, and present solutions that are helpful for developing robust analytical methods. ◆ Development of testing methods using the analytical method and method development software Fusion Dr. Taiki Kamiya, Kaken Pharmaceutical Co., Ltd. The analysis department of the CMC Center, to which the speaker belongs, has been developing testing methods using HPLC and introduced Fusion four years ago to improve operational efficiency. This time, we will explain the introduction environment, background, and overview of Fusion, and introduce the operational methods used in the department. Additionally, we will share impressions of using Fusion (advantages and challenges) as well as examples of testing method development (successes and failures). ◆ Waters Analytical Development Solutions, Waters Japan We will introduce mass spectrometers that can be used in conjunction with QbD software, LC systems that enable smooth development and transfer of analytical methods, and the quality of analytical columns, which is crucial for conducting robust analyses over the long term.

In recent years, with the advancement and enhancement of polymer materials, various additives for synthetic polymers with different functions have been used in optimized formulations. Among them, there are types of additives, such as hindered amine light stabilizers (HALS) and lubricants, that present challenges in solubility and detection methods, making analysis difficult. Additionally, when conducting structural analysis of multi-component polymers or terminal group analysis using pyrolysis gas chromatography-mass spectrometry (PyGC/MS), there are many pyrolysis products not registered in the EI method database, making analysis not straightforward. In this webinar, we will introduce two solutions to the challenges in the characterization of synthetic resins, along with practical examples. ■ Overview of additives for synthetic polymers ■ Actual quantitative analysis of HALS/lubricants ■ Examples of structural analysis of synthetic resins using PyGC/Q-Tof MS Target audience: Individuals handling organic compounds for the development and quality control of materials and industrial products.
