Hilic separation

WebThe separation achieved was similar on the 2 columns. However, the epinephrine/norepinephrine pair were slightly better separated on the Poroshell 120 HILIC column. Overall, the peaks were sharper on the Poroshell 120 HILIC column, and the last peak eluted at 3 minutes versus more than 6 minutes on the ZORBAX Rx-Sil column. … WebThe HILIC separation was achieved using a simple mobile phase composed of 20 mM ammonium acetate at pH 9.0 in a 70:30 v/v acetonitrile:aqueous solution. This composition is appropriate for MS and UV detection. Good peak shapes were achieved for the compounds by utilizing MaxPeak Premier High Performance Surfaces (HPS) Technology.
