Agilent Technologies SPE-Kartusche Mega Bond Elut-AL-A, 1 g, 6 ml, 30 St/Pkg

Alumina, like silica, is an extremely polar sorbent. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalized silica. The small particle size of the Bond Elut Alumina range ensures high extraction efficiency even when small bed masses are used.
