Analytical process of the controlled conversion of species originally present in a sample into forms with improved chromatographic yield or separation coefficient. The most popular is derivatization of ionic or highly polar species into non-polar species that can be readilly separated by GC (e.g. Grignard derivatization).

The term "derivatization" was found in the following pages:
