Bonded Packed Column Stationary Phases

• Low bleed levels.
• Longer column lifetimes.
• Short conditioning times.

Bonded phases are used in capillary columns because they provided a dramatic increase in column quality. To truly bridge the gap between traditional packed columns and capillary columns, it was necessary to develop bonded liquid phases for packed columns. Now packed column chromatographers can expect shorter conditioning times, lower bleed, and longer column lifetimes by using Restek bonded phase packed columns.

Solvent rinsing during the manufacturing process removes low molecular weight polymer fragments that contribute to long conditioning cycle times. Our bonded packings usually stabilize in 30 minutes or less. Because the bleed is lower with bonded phases, detectors can be operated at higher sensitivities and the need for data system bleed compensation is greatly reduced.

Bonded phases also last much longer than non-bonded phases. Bonded phases are more resistant to oxidation than non-bonded phases because of the stronger intermolecular forces produced by cross-linking. Because the material is thoroughly cross-linked, the phase will not sag, as often happens with non-bonded phases.These columns are for on-column injections. For not-on-column configuration, add suffix -901.
