Selection of a similar phase with similar 12 intermolecular forces will allow more interaction between the separation column 13 and structurally similar analytes and increase their retention time in the column.
HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC)
webhost.bridgew.eduColumn Role is to separate the components of a mixture Column – Cont. Much shorter than columns used in GC --- Why? Highly efficient separations achieved in HPLC due to interactions of both m.p. and s.p. with the components of a mixture vs. GC, where only the s.p. interacts with components No need for long columns
