Agesin® SPA-MetSil-SH is a high-performance, thiol-functionalized silica gel designed for the selective removal and recovery of metal ions. This metal scavenger exhibits excellent adsorption capacity for soft metals, particularly palladium (Pd), platinum (Pt), and gold (Au), enabling purification to ppb levels. It features a robust silica backbone, good chemical and physical stability, and performs effectively in both aqueous and organic phases across a wide range of temperatures and pH levels.
