Agilent MassHunter ( a) Qualitative Workflows and ( b) Profinder interface. 385 components were extracted from a typical QC sample from 14.5 to 56 min, of which 62 were confidently annotated with match factor ≥ 80. Data was then exported to a CEF file. The file was then used by Profinder for batch data extraction. The Profinder tool was designed with the use of reference spectra and retention time windows to assist data extraction.
