GC Column Application Database

Expansion of •red® branded products continues with the launch of ‘DR-‘ fused silica capillary GC columns. The GC column range includes:

columns for routine applications from the low polarity DR1 to the very high polarity DR-10
columns for high speed separations – narrow bore, thin film columns for lightening fast GC separations
columns for high temperature separations, extending …more


Cyclodextrin Chiral GC Columns

Cyclodextrin Chiral GC Columns gc

Cyclodextrins are oligosaccharides formed from the bonding of six to twelve glucopyranose (sugar) units into a cyclic, cone shaped structure. The number of sugar units varies from 6 to 12. Three sizes are commonly used in the manufacture of commercially available GC phases: alpha, beta & gamma corresponding to 6, 7 and 8 glucopyranose units …more


GC Column Retention Gaps

Conventional retention gaps offer a wider range of applications than Intelligent Retention GapsTM.
Typical uses are automated on-column injection, direct injection of large volumes and/or dirty samples.
Conventional retention gaps are lengths of fused silica tubing internally deactivated for:

General purpose applications
Apolar solvents
Polar solvents

Retention gaps are supplied without press-fit or ferrule type connector which are available separately.
Lengths available …more


Intelligent Retention Gap

•red® capillary  GC columns can be supplied with an ‘intelligent’ retention gap for use at the injector end of the column.
These are an extension of the analytical column tubing with no union required between the deactivated and analytical column sections.
In addition, columns can be produced having the deactivated section at the detector end either as …more


Permeation Tubes

For use with the Permeation Calibration System.
The permeation tubes are teflon / PTFE tubes filled with a specific component in a liquid-vapor phase. The permeation rate of the tube is a direct function of the temperature.
Tubes are supplied with a Certificate of Calibration showing permeation rate in ng/min plus expected useful lifetime of the permeation …more
