Surface Treatment & Plating Bath Analysis
Surface Treatment & Plating Bath Analysis
Surface treatment and plating processes depend on precise chemical control to ensure consistent product quality, reliable performance, and regulatory compliance.
From chromium plating to copper and nickel systems, accurate monitoring of acids, metals, and additives is essential for maintaining stable bath chemistry and preventing costly defects.
Automatic potentiometric titration provides a powerful solution for modern laboratories by delivering:
- High precision and repeatability
- Automated calculations and reporting
- Reduced operator variability
- Faster, more efficient workflows
Compared to traditional manual titration, automated systems significantly improve consistency and traceability of results .
✅ SECTION: WHAT CAN BE ANALYZED
Comprehensive Plating Bath Analysis Capabilities
Modern plating solutions require monitoring of multiple chemical components, including:
- Metal ions (Ni, Cu, Zn, Cr)
- Strong acids (H₂SO₄, HCl, HNO₃)
- Buffer systems (boric acid)
- Additives and reducing agents (formalin, hypophosphite)
- Oxidizers and redox species
- Chloride and other ions
Using automated titration, these components can be measured individually or sequentially in a single workflow.
