1.9.1.1 Typical applications
You typically use product ion spectrum for the following applications:
• Method development for MRM screening studies:
• Identifying product ions for use in MRM transitions.
• Optimizing CID tuning conditions to maximize the yield of a specific product ion to be used
in MRM analysis.
• Structural elucidation.
