CI’s family of wet process concentration analyzers (WetSpec line) offers cost effective solutions for in-line wet chemistry monitoring. These products range from conductivity and NDIR solutions for simple chemistries concentration measurement, to spectroscopic systems for measuring multiple constituents and residues in complex solutions. The main concentration monitoring application that are served by CI Semi’s products are cleaning (SC1, SC2…) etching (HF, BOE, MAI….) and photo resist strippers (EKC, ACT, Piranha….).
