Sample elution was then performed at the University of Bath (UK) following the protocols found in mL of MeOH at a flow rate of 1 mL min -1 into silanised glass vials . The extracts were then dried under a flow of nitrogen using a TurboVap evaporator (Caliper, UK, 40 °C, N2, <5 psi). Reconstitution was performed using 500 µL 80:20 H2O:MeOH before being transferred into polypropylene vials ready for analysis.
