• VertiPak™ PH SPE is moderately non-polar, hydrophobic
sorbent, manufactured using a trifunctional silane and
endcapped to reduce the polar secondary interactions
associated with surface silanol groups.
• Less retentive than VertiPak™ C18 and exhibits a different
selectivity from VertiPak™ C18 or VertiPak™ C8 due to
the electron density of the phenyl ring.
• Typical applications includes molecules of wide range of
polarity in water or aqueous biolgical samples e.g.
aflatoxins in foods, caffeine in serum, phenols in water.
• 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.
