14. Mass spectra were obtained on a quadruple/time-of-flight (Q-Tof) instrument (Micromass, Manchester, UK). The samples were infused into the Z-spray source by a syringe pump at 10 μL/min. Fragmentation was performed by using argon as the collision gas. The acquisition mass range was from mlz = 90 to 700, and 20-50 scans were averaged to produce the spectra.
