Katayama Chemical Industry / Waters Co-hosted Live Webinar The results of research are determined "before analysis"! The reliability of research results is greatly influenced "before analysis," and the key to this is sample pretreatment. Pretreatment determines sensitivity, reproducibility, and efficiency, but in practice, it is often done "as usual" or "somehow," which can lead to variability in results and problems. In this seminar, we will clearly explain the basics of sample pretreatment, which is essential for LC analysis, incorporating the latest insights from both theoretical and practical perspectives. We will specifically introduce how to choose, use, and optimize solid-phase extraction (SPE). 【Program】 - What is sample pretreatment? - Basics of solid-phase extraction (SPE) - How to choose and use solid-phase extraction products - Steps for optimizing solid-phase extraction methods

We will have customers who are active at the forefront of PFAS research and analysis take the stage to introduce their efforts and case studies on PFAS research and management using pretreatment and analytical techniques. Additionally, we will provide an opportunity for information exchange with the speakers, so please join us. ■Invited Lectures Introduction of research on PFAS emission control in the waste treatment and resource recovery process and future prospects Hidetoshi Kuramochi, National Institute for Environmental Studies Analysis of 44 PFAS substances in water quality Jun Yamamoto, Ideah Co., Ltd.

We will hold a webinar series delivering knowledge and know-how about GPC/SEC over four sessions. GPC/SEC is highly specialized and requires specific skills to use correctly. In this series, we will carefully explain common questions and challenges faced by GPC/SEC users, covering everything from basic principles to equipment and column management, calibration, molecular weight calculation, and troubleshooting, with the aim of enhancing your ability to handle these issues independently after viewing. We will also introduce support systems to facilitate analysis operations, as well as examples of the latest technologies combined with ultra-fast GPC systems and mass spectrometers (MS). Session 1: Basics of GPC/SEC Date: October 7 (Tuesday) Session 2: Calibration Curves for GPC/SEC Date: October 21 (Tuesday) Session 3: Molecular Weight Calculation for GPC/SEC Date: November 4 (Tuesday) Session 4: Troubleshooting for GPC/SEC Date: December 2 (Tuesday) All sessions: 15:00 - 16:00

Twenty years have passed since Waters launched the world's first ultra-high-performance liquid chromatograph (UPLC), and with the inclusion of <2.00> General Principles of Chromatography in the Japanese Pharmacopoeia, more people are becoming interested in speeding up LC analytical methods. On the other hand, we hear voices saying, "I understand the benefits, but it's difficult to adopt it for quality control methods in the current situation," and "I don't know what other applications there are besides adopting it for quality control methods." In this webinar, we will focus on the development of analytical methods among the various applications of high-speed and high-resolution analysis, explaining the transfer of analytical methods from UPLC to HPLC, points for column selection, and the differences between HPLC and UPLC systems.

The structural analysis of by-products and unknown impurities in organic synthesis is an extremely important process in various fields such as pharmaceuticals, pesticides, food, and chemistry. The necessity for this analysis is increasing year by year due to the need for quality improvement of products, including impurity profiling in pharmaceuticals and pesticides, the trend of regulatory strengthening in the health food sector, and the impact of trace impurities on the quality of chemical products. Generally, structural analysis widely utilizes methods such as NMR after separation and purification; however, these methods pose challenges due to the significant time and effort required. Against this backdrop, there is a growing demand for rapid and high-precision analytical methods that complement traditional techniques. In this webinar, we will introduce a comprehensive profiling analysis workflow for synthetic by-products and impurities using the SmartMS - ACQUITY RDa mass spectrometer, which incorporates innovative technology and completely eliminates the complexities of high-resolution mass spectrometry, along with the waters_connect UNIFI software, which excels in large-scale data analysis. Participants will experience the latest solutions through demonstrations of the software.
