Resolving duplicate transitions
When you create multiple analytes that share precursor and product transition m/z values, the match between analytes and channels can be ambiguous.
One example is analyzing transitions from isomeric analytes that elute at different times but share the same mass (are isobaric).
If the duplicate transitions are in the same channel (for example, isomers in one channel), the QUAN Review application processes the data correctly without ambiguity. However, if you have identical transitions in different channels (for example, isomers acquired in separate channels), you must associate each analyte with the correct channel in the QUAN Review application.
You are informed of this ambiguity by a warning triangle
on the
OVERVIEW dashboard.

Notes:
- You also see the warning triangle when you examine the embedded method, and you can resolve duplicate transitions in a similar way from that page.
- You also see the warning triangle for duplicate transitions in the same channel. However, you do not need to resolve these duplicates. You only need to resolve duplicates that belong to different channels.
