Agilent CP-Select 624 CB GC Columns

Agilent J&W CP-Select 624 CB GC column, a 6% cyanopropyl, 94% dimethylpolysiloxane phase, is a highly reproducible version of the popular 624 phase and has two to three times lower bleed than conventional columns (bleed specification for a 30m, 0.53mm, df = 3µm is 9pA). It is synthesised and fully characterised to ensure maximum column-to-column reproducibility.

For an even lower bleed performance we recommend the VF-624ms.
