GammaBond Alumina

by ES Industries

GammaBond™ Alumina                                     

  • Stable from pH 1.3 to 12
  • Efficiencies to compete with the best silica based columns
  • Available in low load RP-1 and octyl based RP-8
  • GammaBond RP-1 is used for USP method L29

 

GammaBond Alumina is a family of exceptionally stable alumina-based HPLC columns designed for extreme pH applications to provide high efficiency and unique selectivity. GammaBond Alumina is manufactured by bonding a polymer to a highly stable porous spherical 5 μm alumina particle. This proprietary manufacturing process yields polymercoated packings with the same high efficiency as traditional silica columns, but with all the advantages of alumina. The ES Industries’ GammaBond reversed phase columns may be used with any mobile phase from pH 1.3 to pH 12, and any desired buffer system or additive. GammaBond Alumina is available in two stationary phase types: GammaBond RP-1 and RP-8. Gammabond RP-1 is a low load polybutadiene coated alumina. This phase is used for USP method L-29. GammaBond RP-8 is an alumina based polysiloxane polymer to which n-octyl groups are appended.

Similar columns from other manufacturers to GammaBond Alumina

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
