•VertiPak™ AL-A SPE is acidic alumina, extremely polar
sorbent and more stable under high pH conditions than
silica. •Acid washing of Alumina results in a cationic surface
with decreased capacity for basic compounds. Compounds
are retained by ion exchange with the positively charged
surface or by specific interactions with the metal centre. •Typical applications include neutral acids, anionic
compounds. •Tube format is available in 7 tube sizes. •Cartridge format is available in 300mg and 600mg size. •Tubes or cartridges are packaged in zip sealing bag
protective from moisture and light. •Includes a Performance report including the QC results,
