| 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. |

Every Quadrex capillary column
undergoes stringent testing utilizing either a modified Grob test mix or
application-specific test mix prior to shipping. An actual Capillary Column
Test Data Sheet, which includes the test chromatogram, operating conditions,
and general column information accompanies every column we ship.
For more information on the Grob Test, click
here.
