Features
- High selectivity for amino acids, amines, and furans
- Thermally stable
Mechanism Observations
- Alkyl chain on analyte contributes to chiral recognition
- High sample capacity, therefore, primary surface interactions
Size Selectivity
The influence of the inclusion mechanism on selectivity is much reduced and capacities are, therefore, generally higher.
