In the analysis of trace components such as pharmaceuticals, veterinary drugs, and additives contained in biological samples, solid-phase extraction (SPE) is essential for sample preparation. To achieve high-sensitivity and robust analysis, it is important to establish optimal SPE methods; however, method development and condition optimization require significant time and experience, and there is a strong demand for efficiency given the limited development resources. In this webinar, we will introduce specific approaches for constructing optimal solid-phase extraction methods in a short time, as well as strategies for speeding up development using the Andrew+ dispensing system, illustrated with real examples. The content will also be useful for those who are not considering the introduction of a dispensing machine, providing insights into the concepts of solid-phase extraction method development and efficiency improvements. ■ Program - Efficient solid-phase extraction method development - Easy automation of solid-phase extraction tasks ■ Recommended for - Those involved in bioanalysis in the pharmaceutical and food sectors - Those interested in improving the efficiency of solid-phase extraction

In April 2026, the announcement of the nineteenth revision of the Japanese Pharmacopoeia is scheduled. This revision is expected to apply the general testing method "＜2.00＞ General Principles of Chromatography" for the first time to two items: "Dapagliflozin Propylene Glycol Hydrate" and "Dapagliflozin Propylene Glycol Tablets," which will be newly included. Therefore, in this webinar, we will first review the overview of "＜2.00＞ General Principles of Chromatography." Based on that, we will explain the points for accelerating analysis methods utilizing the "changes in particle size and column length of the analytical column" permitted by this testing method, along with practical examples. Additionally, using the testing method for "Dapagliflozin Propylene Glycol Hydrate" as an example, we will also introduce countermeasures for items that may affect test results.

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
