For use with \"An Open-Source R-Based Workflow for Qualitative and Quantitative Lipidomics of Bovine Milk\". Chromatography used a fast (10 minute) non-aqueous reversed-phase UHPLC separation. MS analysis was performed on a ThermoScientific QExactive Orbitrap high-resolution, accurate-mass mass spectrometer operated in electrospray ionization (ESI) mode.</p><p dir=\"ltr\">Resources in this dataset:</p><ul><li>Resource Title: Bovine Milk Data acquired 06/10/21 File Name: ByrdwellData_Milk_061021.zip Resource Description: Sequence of runs containing 10 Blanks, 30 Standards (6 Levels x 5 replicates), and 48 Bovine Milk extracts, as follows: 2 Cows, 3 feeding periods, 2 days (samples) per feeding period, 4 replicates for 24 samples per cow x 2 cows. 88 runs (separate data files) altogether. All files originally in proprietary .RAW format converted to .mzML. Data obtained on ThermoScientific QExactive orbitrap high-resolution, accurate-mass mass spectrometer.</li></ul><p></p>" ;
