Acetonitrile (with 0.1% formic acid) served as the solvent for the SCMS experiments at a flowrate of 150 nL/min. The mass spectrometer was configured with mass ranges of m/z 200-1500 in positive ion mode and m/z 70-900 in negative ion mode. Additional mass spectrometer settings include a mass resolution of 120K (at m/z 200), ionization voltage of 2.9 kV in positive mode and -2.1 kV in negative ion mode, one microscan, a maximum injection time of 100 ms, and the use of an automatic gain control (AGC) Standard.
