Now you see it, now you don't: unidentified plasma amino acid peak
The amino acids were quantified using a norvaline internal standard against standard curves generated from traceable calibrators using the following ions and (qualifier ions): alanine--mz 130, sarcosine--mz 217, and norvaline--mz 158.
