Panel discussion: the value of HRMS vs. QQQ for DMPK studies

The aim of DMPK is to enable scientists to learn the safety and efficacy of new molecular entities. HRMS is an important analytical tool used to study DMPK that continues to gain traction when quantifying molecules.

New generations of HRMS systems have the capability of providing both quantitative and qualitative data and are increasingly being adopted due to their ease of use, run speed, accuracy and specificity. With the number of approved biotherapeutic drugs increasing each year, is it important that technologies and platforms are suitable to characterize DMPK.

This free panel discussion will feature a variety of expert panelists from across the bioanalytical field, with each panelist providing insights into their research and use of HRMS. Throughout the discussion, the panelists will explore the changing usage of HRMS, how HRMS compares with QQQ, the most common challenges encountered in the field and their opinions on what the future holds.


What will you learn?

  • The most popular applications for HRMS
  • The unmet needs that apply to daily work with QQQ
  • The main hurdles of using HRMS for quantification
  • The potential future developments for this increasingly popular technology
