Sample preparation for LC-MSMS is often thought of as a necessary evil. The topic is complex and there is conflicting advice about what technique to use. The default choices are dilution and protein precipitation because of their ease of use. This presentation will discuss how to proceed when a more complex and/or expensive sample preparation protocol than those defaults is under consideration. Proceeding step-by-step through an example, the goal is to demystify for the new user the processes of selecting, evaluating, comparing, optimizing and performing pre-validation studies with the common LC-MSMS sample preparation protocols used for small molecule quantitation.
