Scavenger Solutions are available for the metals highlighted in blue in the Periodic Table.
Notable - Scavengers for Ni, Cu, Cr and Fe achieving <0.1 ppm
Stricter enforcement and lower regulatory residual levels require more effective Scavengers.
Si-Novation Smart Novel Technology meets these and future regulatory lower levels.
