polar phase Crossbond polyethylene glycol Restek&rsquos polar-deactivated surface tightly binds the Carbowax polymer and increases thermal stability, relative to competitive columns. Because of the increased stability produced by the bonding

porous divinylbenzene homopolymer Porous polymers are unique, highly retentive stationary phases with a wide application range that are able to elute both polar and nonpolar compounds. They are very hydrophobic, so water has no impact on retention

polar phase Crossbond base-deactivated Carbowax polyethylene glycol&mdashfor amines and basic compounds Stabilwax-DB columns reduce adsorption and improve responses for many basic compounds, without analyte derivatization or column priming. For

Brownlee Aquapore C8 columns are based on wide pore 300 7µm silica, for the analysis of large bio-molecules. Requires holder P/N 07150014 without guard column or P/N 07150016 with a guard column.
