Chromatography Summary:The apparatus consisted of a two LC-20AD pumps (Shimadzu, Japan), an automatic sample injector, coupled on-line with an LCMS-IT-TOF (Shimadzu, Japan) mass spectrometer with an electrospray ionization source. The HPLC separation was conducted on a 2.1 × 100 mm Waters Acquity UPLC BEH; 1.7 μm column (Waters, Milford MA, USA) with 2.1 × 5 mm UHPLC Guard 3PK Zorbax SB-C18 1.8 μm guard column (Agilent Technologies, USA). Two solvents were used: (A) deionized water with 0,1% formic acid, and (B) MeCN. After a 5 min hold at 5% solvent B, elution was performed according to the following conditions: from 5% B to 40% B in 20 min; to 95% B in 7 min; keeping constant for 10 min, to 5% B in 3 min, followed by 5 min of equilibration on the initial conditions. Total analysis time was 50 min. Column temperature was 35˚C. Autosampler tray temperature was 4˚C.
