Product Description
Features and Benefits
- Four achiral SFC selectivities
- Two-stage functionalized BEH particles
- Good peak shapes with reduced additive requirements
- 1.7 and 5 µm particles
- Scalable from analytical to preparative
Additional Notes
Torus phases are produced through a two-step functionalization of BEH hybrid particles. This surface architecture shields against undesirable interactions with the base material and allows for the targeted adjustment of achiral SFC selectivities. 2-PIC, DEA, DIOL, and 1-AA differ significantly in basicity, polarity, aromaticity, and hydrogen-bonding ability. This enables broad selectivity screening to be conducted within a common particle base and allows an analytical method to be transferred to preparative Torus formats.
