As previously mentioned, a XEVO triple quadrupole mass spectrometer was used. This method was in ESI positive mode. The source desolvation temperature was at 400 °C. Regarding gas flows, the cone gas was at 100 L h -1 and the desolvation gas was at 1000 L h -1 . Argon was used as the collision gas and nitrogen for the nebulising and desolvation gas. Full breakdown on specific compounds transitions and collision cell energies may be found in Holton et al. .
