Sample Set Information

ID SE126
Title Test dataset for MS-DIAL 2.0 and MS-FINDER 2.0
Description Three validation kits are prepared for the evaluation of MS-DIAL 2.0 and MS-FINDER 2.0.

(1) The validation of MS-DIAL chromatogram deconvolution for GC/MS data was performed by six raw data files from five major MS vendors.
(2) Software comparison of MS-DIAL against other alternative programs was performed by four raw data files.
(3) Software comparison of MS-FINDER against other alternative programs was performed by five EI-MS spectra.

The raw files except for Bruker Daltonics and Thermo Fisher Scientific (because of their contracts) can be downloaded.

Description Extraction procedures

All metabolite extraction procedures were kept on ice, and the quantities for sample aliquots were 25 μL for blood plasma, 5 x 10^6 for cells, 5 mg for tissues, and 2 mL for algae cultures. Metabolites were extracted with 1,000 μL of degassed acetonitrile:isopropanol:water (3:3:2, v/v/v) and then homogenized, centrifuged, decanted, and evaporated. Extracts were cleaned with 500 μL of degassed acetonitrile:water (1:1, v/v) to remove triglycerides and membrane lipids, and evaporated again. For GC-MS analysis, internal standard C8–C30 fatty acid methyl esters were added to determine the retention index. The dried samples were derivatized with 10 μL of methoxyamine hydrochloride (or ethoxyamine hydrochloride) in pyridine and subsequently by 90 μL of MSTFA (or MSTFA-d9) for trimethylsilylation of acidic protons.

Analysis procedures were done according to the "LECO GC-TOF MS" protocol from a previous report.
