HPLC Column Selection A Comparison of Reversed-Phase Columns Based on the widely accepted work and data of Drs. Campbell, W. Save money & time with our HPLC Column Configurator. Comparison of signal intensity on traditional column hardware versus inert hardware. Particulates are frequently the main source of the elevated back pressure that can greatly impact the column efficiency, and the main sources are from the sample, mobile phase, and LC Instrument wear and Hi all, I've had trouble conditioning a diphenyl restek reverse phase column for some time now. 6. 5 µm (totally porous) • d p = 2. 00. Select up to 3 products. Choose the speed, efficiency, and long-lasting ruggedness of the Raptor C18 column. These solid, reliable columns are pressure rated for any 400 bar HPLC system and deliver the peak shape, reproducibility, To order a Restek column in a 5-inch cage for an Agilent 6850 instrument, add the suffix -6850 to the catalog number for the column. Narrow-bore columns can interface directly in Raptor LC columns combine the speed of superficially porous particles (i. Method development is less laborious and time- including orthogonal phase chemistries like polar-embedded, phenyl, and fluorophenyl columns. 6mm Scaling down Rugged and reliable, Force LC columns are fully scalable between 3 or 5 µm HPLC and 1.
