Event Overview:

The webinar, Overcoming Impurity Challenges: The Importance of Ultrapure Water in Liquid Chromatography (LC), will explore the critical role of ultrapure water in enhancing the accuracy and reliability of LC analyses. It will cover various types of contamination that can affect LC performance and how these contaminants impact results. The session will highlight the advantages of using water purification systems, particularly the Sartorius Arium® systems, which provide high resistivity, low total organic carbon, and minimal bacterial content, ensuring optimal chromatographic results. Case studies will demonstrate the effectiveness of freshly produced vs bottled ultrapure water in different applications, such as CHO-cell mAb production, organic molecules, as well as PFAS analysis, showcasing Arium®’s ability to reduce various impurities and improve data quality. The webinar will also introduce the new Arium® Mini Extend, designed for labs with limited space, offering flexible water dispensing options and cost efficiency.

Key Learning Objectives:
  • Understand ultrapure water's role in LC accuracy
  • Learn about contamination impacts on LC results
  • Discover Arium® systems' benefits and the new Mini Extend
Who Should Attend:
