MS:

MS ID:MS004317
Analysis ID:AN004571
Instrument Name:Agilent 5977A
Instrument Type:Single quadrupole
MS Type:EI
MS Comments:The data was analyzed using MS-Dial (version 4.9) for peak detection, deconvolution, alignment, quantification, normalization, and identification. Putative identification of the metabolites was based on the Kovats retention index (RI) and the matching score of the mass spectra with the libraries. Two libraries were used, a local library made from running authentic standards with Kovats RI, and a public spectrum library, the curated Kovats RI with a total of 28,220 compounds (last edited August 21th, 2022, which includes the Fiehn, RIKEN and MoNA databases). The peaks were manually curated reviewed for peak shape, chromatogram alignment integrity and MS/MS match, and the final list of compounds with RI similarities >95% were report-ed. The data was normalized based on the internal standard spiked in the samples during extraction and using LOWESS (locally weighted scatterplot smoothing) for QC-batch normalization.
