SiliaMetS® TAAcOH (SiliaMetS Triaminetetraacetic Acid) is a silica bound metal scavenger for Pd(0), Ni(0) and Cu. It is the supported version of EDTA in its free form. It is an effective scavenger for metals in low or zero oxidation states, which includes many of the most synthetically useful catalysts such as tetrakis-(triphenylphosphine)palladium(0).

Best scavenger for: Ca, Co, Ir, Li, Mg, Ni, Os, Ru & Sc

Good scavenger for: Cr, Cs, Fe, Pd, Rh & Sn

SiliaMetS® TAAcONa or (or SiliaMetS Triaminetetraacetate, sodium salt) is a silica bound metal scavenger for Pd(II), Ni(II) and Cu. It is the supported version of EDTA in its sodium salt form. It is an effective scavenger for metals in higher oxidation state, 2+ or higher.

Best scavenger for: Ca, Cd, Cs, Cu, Fe, Ir, La, Li, Mg, Ni, Os, Rh, Sc & Sn

Good scavenger for: Cr, Pd, Ru, Se & Zn

SiliaMetS Thiourea (Si-THU) is a versatile metal scavenger for all forms of palladium and is widely used in the pharmaceutical industry. It works particularly well in organic solvents.

Best scavenger for: Pd & Ru

Good scavenger for: Ag, Cu, Fe, Os, Rh, Sc & 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 TMA Chloride (SAX) is a strong anion exchanger sorbent positively charged under all conditions used to extract acid molecules (pKa 3-5).
