Dimethyl modified silica phases for HPLC |
3.5 % C · USP L16 |
Non-endcapped phase for RP and ion-pairing chromatography Pore size 100 Å, particle size 7 µm pH stability at 20 °C: 2–8 Retention times are much shorter than for the other RP phases Separation mechanism based on hydrophobic (van der Waals) interactions; noticeable silanol interactions |
