Chromatography separates mixture components based on differential sorption/mobility through mobile and stationary phases.
Trin-for-trin guide
- 1Input sample composition, phase properties
- 2Calculate retention factors and separation factors
- 3Predict resolution and peak positions
Løste eksempler
Input
Thin-layer chromatography: Rf = distance traveled / solvent front distance
Resultat
Components separated by mobility differences
Almindelige fejl at undgå
- ✕Not optimizing mobile/stationary phase
- ✕Ignoring sample concentration (affects resolution)
Ofte stillede spørgsmål
Types of chromatography?
Gas, liquid, thin-layer, ion-exchange, gel permeation; choose based on sample properties.
