PARAFAC signal intensity for cerebrum standard that does not contain BMAA in (A) Column one retention time window, and (B) Column two retention time window. (C) PARAFAC reconstructed total ion current (TIC) showing lack of BMAA peak. (D) Mass spectral data from PARAFAC analysis shows that BMAA was not detected. Non-bold lines in panels (A) and (B) indicate loadings that are due to noise, baseline, or other analytes See ref [32].
