Figure 9-6. HPLC/APCI-MS chromatogram of the randomized mixture of OOO (D9-C18:1) and EEE (D9t-C18:1) using Ag-HPLC with three ChromSpher Lipids columns with a total length of 75 cm, flow rate 1 mL/min, column temperature 25oC, gradient of hexane-2propanol-acetonitrile. Ag-HPLC, silver-ion high performance liquid chromatography; APCI, atmospheric pressure chemical ionization; MS, mass spectrometry.
