SiliaPrep Silica is the most polar sorbent presenting a slightly acidic character used to extract various compounds from non-polar solvents using hydrogen bonding. Efficient sorbent for the separation of analytes with similar structures and for removing the baseline noise from organic samples.

SiliaMetS^® Thiol (Si-Thiol) is our most versatile and robust metal scavenger for a variety of metals under a wide range of conditions.

Best scavenger: Ag, Hg, Os, Pd & Ru

Good scavenger: Cu, Ir, Pb, Rh & Sn

SiliaPrep TMA Acetate (SAX-2) is a strong anion exchanger sorbent with a low selectivity acetate counter ion already in place. This sorbent retains more favorably acidic compounds with pKas <5, such as carboxylic acid.

SiliaPrep Tosic Acid is a strong cation exchanger and maintains a negative charge throughtout the pH scale. The most common use is a strong cation exchanger for the amine and basics molecules “catch and release” purification technique in SPE cartridges.
