#Unit 13. Methods in Biology

In Normal-phase liquid chromatography the stationary phase is polar and the mobile phase relatively non-polar.

#Unit 13. Methods in Biology

In NPLC the most popular stationary phase is an alkylamine bonded to silica. The mobile phase is generally an organic solvent such as hexane, heptane, dichloromethane or ethyl acetate.

#Unit 13. Methods in Biology

The main applications of normal-phase liquid chromatography are its use to separate
analytes that have low water solubility and those that are not amenable to reversed phase liquid chromatography.

The pH of the buffer selected as eluent should be at least one pH unit above or below the isoionic point of the analytes.
