LCMS Data Interpretation The following chromatogram shows the base peak chromatogram (BPC) overlaid with an extracted ion chromatogram (EIC) at mass 663. Why do we see multiple peaks in the EIC 03 Your Notes: Please summarize your thoughts about relationships between the ions observed in the mass spectrum. Your Notes:

Solution

These are the possible fragments of the molecule. The values are not visible, so difficult to correlate.

The structure of the compound will be helpful for the interpretation of the LCMS data.

It is also important to understand whether the sample is a pure one or has got some other related or non-related impurities in it.
