Have you faced an LC-MS/MS problem — resolved or still in progress? Share your experience with the clinical laboratory community at MSACL 2026. No issue is too simple or complex: method development, validation, or day-to-day production troubleshooting are all welcome. If you learned something, chances are others will too.

How it works Selected submissions will be presented at the Troubleshooting Cases Forum. Presenters give a brief 3–5 minute summary covering:

The problem encountered
The troubleshooting steps taken
Insights or lessons learned

A panel of experienced users — plus any interested attendees — will then join the discussion, offering perspectives and suggestions. The session is informal and collegial, with one goal: mutual learning.

Ready to submit? Submitting a Troubleshooting Case does not affect your eligibility to submit a scientific abstract — you can do both. Abstracts not selected for a Forum Presentation will be considered for Poster Presentation. Submit your Troubleshooting Case abstract by July 31, 2026. Troubleshooting Positions have been assigned as of June 17, 2026.

The Troubleshooting Cases Forum will be held in Montreal 4.
