Phenyl HPLC Semi-Prep
The Phenyl terminal group bonded phase has sp2 character and is frequently used when the main differences between the analytes involve π-π interactions. However, keep in mind that π-π bonds are quite weak in comparison with hydrogen bonds, van der Waals forces, and electrostatic bonds. If water is in the mobile phase, as it usually is in Reversed Phase mode, the π-π interactions will be very weak by comparison and not contribute much to the separation. In Normal Phase mode, the π-π interactions make a significantly greater contribution to retention so separations designed to exploit the differences between molecules based on π-π interactions will be more significant.
Recommended Applications:
- Aflatoxins from food
- Caffeine from beverages
- Flavors
- Phenols from water
- Trace elements from water
For Semi-Prep HPLC and SFC
Phenyl HPLC Semi-Prep is available in porosities of 100Å, 300Å, and 500Å and particle sizes of 5µm, 10µm, and 15µm.
Quality and diversity
Phenyl HPLC Semi-Prep is manufactured on Sorbtech’s Premium RfTM Spherical Silica Gel which boasts narrow pore and particle distributions, ensuring optimal selectivity, capacity, efficiency, low operating pressure, and shorter processing time.
Purity
Premium Rf Spherical Silica Gel is manufactured to a high chemical purity standard (99.95% SiO2). Organics and trace metals content are controlled within stringent limits. Each production batch has undergone extensive quality control testing to ensure reliable lot-to-lot performance. This rigid control of chemical purity, surface area, and pore size, ensure our silica will yield reproducible separation results and allow for direct scale-up without requiring time-consuming method redevelopment.
Robust
Our spherical silicas are mechanically robust and can, therefore, be repacked multiple times in either analytical or preparative scale columns.
