Gamma bond 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 highlystable porous spherical 5 um alumina practicle. This proprietary manufacturing process yields polymer coated packings with the same high efficiency as traditional silica columns, but withall 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 desired buffer system or additive GammaBOnd Alumina is available in two stationary phases types. GammaBond RP-1 and RP-8. Gammabond RP-1 is a low load polybutadiene coated aluimna. 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.

GammaBond Alumina (RP1 or RP8): pore size =80 A; pH range = 1.3-12.
