solid phase extraction
  Products > SPE > VertiPak™ CN

•  VertiPak™ CN SPE is medium polar sorbent that exhibits
    both normal phase and reversed phase interactions.
•  Less retentive than Silica, or Diol for polar compounds.
•  Typical applications include both polar and nonpolar
    molecules from aqueous samples, polar molecules from    
    relatively non-polar solvents using the dipole interactions
    between polar functional groups on the analyte and the   
    cyano group on the sorbent e.g. carbohydrates, cyclosporins.
•  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.
