Chromatography is a technique in which a gas or liquid mobile phase carries the analytes (compounds to be separated) through a stationary phase and then to a detector that measures the analytes one-by-one as they exit the chromatographic system. Match the numerical terms in the first list with the appropriate alphabetical definitions in the second list. Note: choose as many matches as applicable.
1. adsorption chromatography
2. ion-exchange chromatography
3. size exclusion chromatography
4. capillary electrophoresis
Ions in mobile phase are attracted to counterions covalently attached to the stationary
Solute equilibrates between mobile phase and film of liquid attached to stationary
Solute in mobile phase is attracted to specific groups covalently attached to the
D. Solute equilibrates between mobile phase and surface of stationary phase.
E. Different-sized solutes penetrate voids in stationary phase to different extents.
Largest solutes are eluted first.
F. Charged ions are separated based on their electrophoretic mobility with the use of an
G. Migration of compounds occurs due to their different degrees of interaction with the
H. Utilizes a very strong mobile phase (k=0).
