columns designed for extreme pH applications to provide high
efficiency and unique selectivity.![]() |
Chromegabond ODS-PI | C18 (polar imbedded) | 120 | 3, 5 | --- | --- | Chromegabond
ODS-PI is produced by a single step bonding approach and avoids all
the difficulties faced by amide based polar imbedded columns which
suffer poor pH stability and undesirable interaction with acids.![]() |
Chromegabond PSC | C8/C18 | 100 | 3, 5 | 14 | 2 - 8 | Chromegabond
PSC (pharmaceutical separation column) is prepared by using a
mixture of C8 and C18 groups. These columns are able to retain both
highly polar and hydrophobic compounds.![]() |
Chromegabond C22 | C22 | 100 | 3, 5, 10 | 22 | 2 - 8 | The
Chromegabond C22 is ideally suited for the separation of
triglycerides, PAHs, and steroids.![]() |
Fluorinated phases | ||||||
Epic PFP-LB, FO-LB | low-bleed PFP, FO | 120 | 3, 5 | --- | 1 - 10 | With their low
bleed characteristics Epic PFP-LB (pentafluoro-phenyl) and FO-LB
(perfluorinated C8) phases are well suited to the separation of
trace impurities especially for halogenated analytes, lipophilic
compounds and environmental samples.![]() |
Chromegabond PFP-T | pentafluorophenyl | 60 | 5 | --- | --- | One of the
first HPLC columns specifically developed for the analysis of Taxol.![]() |
Chromegabond LS / LS-HS | fluoroaliphatic | 180 / 100 | 3, 5 | --- | --- | Chromegabond LS

fat-soluble vitamins, fatty acids, aliphatic pharmaceutical, and
surfactants.![]() |
Chromegabond FluoroSep-RP Propyl (FP) |

peptides, and other related compounds of medicinal/biological
interest.![]() |
Chromegabond FluoroSep-RP Octyl (FO) |
perfluorooctyl | 60 | 5 | --- | 2 - 8 | The fluorinated
octyl has retention similar to that of standard C8 phases, but with

including enhanced selectivity for halogenated compounds.![]() |
Chromegabond FluoroSep-RP Phenyl (FSP) |
pentafluorophenyl | 60 | 3, 5, 10 | --- | --- | Chromegabond
FSP has been extremely useful in the separation of epimers. It is
also an excellent alternative to ODS columns for the bulk
characterization of pharmaceuticals. Many of the impurities co-elute
with the active compound on ODS columns and even major changes in
mobile phase composition can fail to improve separation.
Chromegabond FSP can often separate these impurities. In addition,
impurities can be more definitively resolved thus improving
quantification and reproducibility.![]() |

provides similar selectivity to silica gel but is considerably less
active. The Chromegabond NPI column also exhibits different
selectivity other than polar bonded columns such as DIOL and CN. An
NPI column is very useful for the separation and isolation of
compounds found in natural products, for steroids and fat-soluble
vitamins.![]() |
Chromegabond Carbohydrate | bonded amine | 120 | 5 | --- | --- | Specifically
designed for the analysis of sugars, sugar alcohols and
oligosaccharides with mobile phases typically composed from 50-95%
acetonitrile and 50-5% water.![]() |
