Quadrex Corporation, Capillary Columns, Fused Silica Capillary Column, 007-10, 007-20, 10 and 20% phenyl methylpolysiloxane

007-10 and 007-20
*10% and 20% phenyl methylpolysiloxane*

Bonded and Crosslinked
Comparable to: OV-3, OV-7
Similar phases: Rtx -20, SPB-20
007-10 and 007-20 (10% and 20% phenyl substitution, respectively) are the Quadrex designations of phenyldimethylpolysiloxane phases. The phenyl substitutions contribute to the "induced dipole" selectivity of these phases. A column coated with either phase displays excellent efficiency and thermal stability. These phases provide an excellent alternative for drug and environmental pollutant analyses where greater retention of aromatic compounds is necessary.

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.

Below are the results of a 007-10 column tested with the Grob Test mix which shows the excellent level of deactivation achieved with this phase.
