| Chromatography Type | HILIC |
| Chromatography Column | Higgins Analytical TARGA C18 (50 x 2.1mm,5um) |
| Solvent A | 100% water |
| Solvent B | 100% acetonitrile |
| Gradient | Initial mobile phase conditions are 22.5% A, 75% B, 2.5% C hold for 1.5 min, with linear gradient to 77.5% A, 20% B, 2.5% C at 4 min, hold for 1 min, resulting in a total analytical run time of 5 min. During the flushing phase (reverse phase analytical separation), the HILIC column is equilibrated with a wash solution of 77.5% A, 20% B, 2.5% C. |
