SiliaMetS® Metal Scavenging Screening Service

Having problem removing any leftover metal catalyst?

Contact us to take advantage of SiliCycle’s expertise in metal removing capabilities. Our R&D team can find the optimal conditions for you.

 confidentiality-assured


Metal Scavenger Screening Services are innovative as they provide an on-hand solution to the pharmaceutical and manufacturing industries. Working with the product that needs to be free of residual metals and the restricted conditions that can be used with the compound (solvent, temperature), SiliCycle’s Metal Scavenger Screening Service will quickly develop the most efficient metal scavenging process (time and cost savings) under confidentiality, as in most of the cases it involves working with API or other patented materials, and will insure an easy technology transfer.

Do like many major pharmaceutical companies and CONTACT US to discuss how we can help you to reach your metal purity goals. Many screening services adapted to customer’s needs & budgets are available.

    SiliaMetS® Thiol

    1 Review(s) | Add Your Review

    SiliaMetS® Thiol (Si-Thiol) is a robust metal scavenger for a variety of metals including Pd, Pt, Cu, Ag and Pb under a wide range of conditions. It has been used in pharmaceutical processes up to the pilot plant scale. It is our most versatile metal scavenger and is the preferred metal scavenger for Pd(II), Cu, Ag, and Hg.

  2. SiliaMetS® Thiourea

    SiliaMetS® Thiourea

    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. It can also be used to scavenge Ag, Pt, Ru, Rh and Hg. Once complexed with a transition metal, it has been reported as being an effective catalyst.

  3. SiliaMetS® Cysteine

    SiliaMetS® Cysteine

    SiliaMetS® Cysteine (Si-Cys) is the silica bound equivalent of the amino acid Cysteine. By attaching the molecule to the backbone via the amino group, the thiol group remains free and accessible for higher metal scavenging efficiency. It is a versatile metal scavenger for a variety of metals including Pd, Sn, Ru, Pt, Cu, Rh, Cd and Sc under a wide range of conditions and the preferred metal scavenger for tin residues.

  4. SiliaMetS® Dimercaptotriazine (DMT)
