Emergency meeting! This time we will focus on the pretreatment of PFAS in environmental samples, as inquiries have surged!

The measurement of PFAS (perfluoroalkyl substances) is becoming increasingly important in the field of environmental testing. In particular, accurate and efficient quantitative analysis is required in complex matrices such as non-potable water, soil, and biosolids, including wastewater and rivers. In light of this, there has been a surge in inquiries regarding PFAS pretreatment in accordance with EPA Method 1633 since the end of last year. Therefore, we will urgently hold a seminar in February to address these challenges, changing our original schedule. 【Event Overview】 ■ Date: February 27, 2025 (Thursday) ■ Time: 13:30 - 14:15 JST (45 minutes) ■ Participation Fee: Free <Pre-registration required> https://register.gotowebinar.com/register/8028605763632700251
