Ultrasep ES 100 Methyl-RP8 is a silica-based HPLC column with a 100 Å pore size and an octyl (C8) bonded phase combined with methyl endcapping. This design delivers moderate hydrophobic retention, faster elution compared to C18, and improved peak symmetry for basic compounds due to reduced silanol activity.
The column provides robust performance, high efficiency, and excellent reproducibility, making it a reliable choice for both routine quality control and method development in reversed-phase HPLC.
Ultrasep ES 100 Methyl-RP8 combines balanced hydrophobic retention, endcapped stability, and reproducible performance – the versatile choice for efficient reversed-phase HPLC separations.
