HPLC–MS

We used an HPLC system, which consisted of a binary solvent delivery system, an on-line degasser, an auto-sampler, a column temperature controller, and a diode array detector. Separation was conducted using a C18 column (5 µm, 150 mm × 4.6 mm), and the temperature was set to 40℃. The injection volume was 0.01 mL, and the flow rate was 1 mL/min. Gradient elution was conducted using a binary system consisting of 10 % formic acid in DW (A) and 10 % formic acid in acetonitrile (B). The utilized gradient was as follows: isocratic 1 % B for 6 min, 1% – 3% B for 4 min, 3 % – 15 % B for 20 min, 15 % – 40 % B for 20 min, 40 % – 90 % B for 5 min, 90 % B isocratic for 10 min, 90 % – 1 % B for 5 min, and 1 % B isocratic for 10 min. A re-equilibration operation followed. The UV detection wavelength was set to 280 nm.

The voltages of the sample cone and the capillary were set to 17 and 3000 V for the positive ion mode and 22 and 2000 V for the negative ion mode.
