• VertiPak™ AL-B SPE is basic alumina, extremely polar
sorbent and more stable under high pH conditions than
silica.
• Basic washing of Alumina results in a anionic surface
with decreased capacity for acidic compounds. Compounds
are retained by ion exchange with the negatively charged
surface or by specific interactions with the metal centre.
• Typical applications include neutral amines, cationic
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,
lot chromatogram and lot recovery test.
