007-23 is a (78% cyanopropyl) methylpolysiloxane and is our most polar phase type. The strong permanent dipole interactions of this phase with unsaturated compounds yields separations according to geometric configurations of the double bonds. The 007-23 phase is ideal for the separation of cis/trans isomers of fatty acid methyl esters (FAMEs) as well as the isomers of dioxins and furans. The 007-23 phase is bonded and crosslinked and the column performance can be restored by rinsing.
