Capital HPLC



Chromegabond is a range of HPLC supports manufactured by ES Industries in the United States. The Chromegabond range is particularly interesting because of the enormous number of derivatised phases which are available. There are a number of exotic chemistries which may be suited to even the most unusual separations, e.g., 
there is a C22 alkyl phase and pentafluorophenyl phase. Many of these phases are exclusive to the Chromegabond range. Chromegabond columns are available from Capital HPLC in all of the various formats in our range from narrow bore to preparative scale.

Available bonded phases include: Methyl, Dimethyl, Trimethyl, n-Propyl, n-Butyl, n-Hexyl, Cyclohexyl, C8, C10, C12, C18, C22, Diphenyl, Pentafluorophenyl, Propylcarboxymethylester,Adamantane,Amine,Diamine, Triamine, Diol,Cyano, Amino, Nitro, Silver Impregnated Silica.

Chromegabond Alumina gRP1 (Polybutadiene) is a special material for the analysis of azythromycin as described in US Pharmacopia (L29). Catalogue No. 5TT115 (see price list page 22.)

New Chromegabond AquaSep

Aquasep is a new reversed phase, developed by ES Industries, which enables highly water soluble
analytes to be chromatographed on a C8 bonded phase, even with purely aqueous mobile phases.
Aquasep is suitable for the analysis of highly water soluble compounds such as small organic acids,
water soluble vitamins, purines and pyrimidines without the need for ion pairing agents.

_ Chromatograph polar compounds with
    pure aqueous mobile phases

_ Rapid re-equilibration with gradients (0-

_No ion pairing agents required for highly
  polar compounds

_Extremely high carbon loading
