| Chromatography Instrument Name | Thermo Dionex Ultimate 3000 RS |
| Chromatography Type | Reversed phase |
| Chromatography Column | Waters XBridge BEH Amide (50 x 2.1mm,2.5um) |
| Solvent A | 100% water |
| Solvent B | 100% acetonitrile |
| Gradient | Initial mobile phase conditions are 60% A, 35% B, 5% C hold for 0.5 min, with linear gradient to 0% A, 95% B, 5% C at 1.5 min, hold for 3.5 min, resulting in a total analytical run time of 5 min. During the flushing phase (HILIC analytical separation), the C18 column is equilibrated with a wash solution of 0% A, 95% B, 5% C until 2.5 min, followed by an equilibration solution of 60% A, 35% B, 5% C for 2.5 min. |
