CP-Select 624 CB

J&W CP-Select 624 GC Columns from Agilent Technologies

Agilent J&W CP-Select 624 CB is a highly reproducible version of the popular 624 phase and has two to three times lower bleed (bleed specification for a 30 m, 0.53 mm, df = 3.00 µm is 9 pA) than conventional columns. The CP-Select 624 CB, a 6% cyanopropylphenyl, 94% dimethylsiloxane phase, is synthesized and fully characterized to ensure maximum column-to-column reproducibility. For an even lower bleed performance we recommend the VF-624ms.

Agilent J&W CP-Select 624 Hexane is a highly reproducible column specifically designed for the separation of hexane isomers and dichloromethane. Application specific QC testing provides assurance for specific separation and column-to-column reproducibility. For residual solvents analysis according to USP <467> Residual Solvents we recommend DB-Select 624 UI for <467>.
