GENERAL AREA OF USE

cis and trans FAME isomers, dioxin analyses

The 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.

007-23, (78% Cyanopropyl) methylpolysiloxane columns are available in 30M. and 60M. lengths with 0.25µm films only.  Column I.D.'s are noted below.

HOT TIP:

The use of oxygen traps is essential when using any cyanopropyl based columns to avoid possible phase degradation from system leaks.
