Liquid chromatography was coupled to a modified ZenoTOF 7600 instrument (SCIEX, Concord, ON, Canada) for analyte detection. Ionization in positive mode was achieved using the electrospray OptiFlow TM Turbo V ion source (Sciex) with the high flow microelectrode, 50-200 µL/min. The source parameters were set as follows: ion spray voltage (SV) 5500V, ion source gas 1 and 2 (GS1, GS2) 40 psi and 60 respectively, curtain gas 35 psi, CAD gas 7, declustering potential (DP) 70 V and temperature 400°C.
