CLEAN-UP® Solid Phase Extraction Columns (SPE). Clean-Up® products are geared towards a variety of extractions. This line is composed of ion exchange, hydrophilic, hydrophobic, copolymeric and covalent solid phase extraction columns.
Clean-Up® Hydrophilic Columns. This sorbent is composed of a silica backbone bonded with carbon chains containing polar functional groups. Compounds are retained on hydrophilic sorbents through polar interactions including hydrogen bonding, pi-pi or dipole-dipole interactions. Examples of groups that have this functionality are amines, hydroxyls and carbonyls. Characteristics: Average pore size = 60 Å. Surface area = 500 m2/g. Pore volume = 0.77 cm3/g.
