| Title | LC-MS based untargeted metabolome analysis of various samples |
| Description | Compounds in various samples were analyzed using liquid chromatography-mass spectrometry (LC-MS). The same analytical conditions are applied to all samples. Therefore, the compound peaks can be compared to each other by the mass values, the retention time of the LC, and the CID mass spectrum. The data were obtained for the construction of the “Thing Metabolome Repository” website (http://metabolites.in/things). |
