•  VertiPak™ NH2 SPE is polar or weak anion exchange sorbent.
•  As a polar sorbent, NH2 is excellent for separation of
    structural isomers. As weak anion exchanger sorbent, NH2
    is Good for retention of very strong acids.
•  Typical applications include lipids, micotoxins.
•  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.
