日本ウォーターズ（米国本社 Waters Corporation）　 Company Profile

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

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.

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.
