Installation instructions for 894 Professional CVS semiautomated: 894 Professional CVS with 800 Dosinos for automatic dosing

Significance of the topic

Precise monitoring of suppressor and brightener additives in copper plating baths is critical for maintaining deposit uniformity, surface quality, and process efficiency. The semiautomated CVS (Cyclic Voltammetric Stripping) approach reduces manual handling, improves reproducibility, and supports stringent QA/QC in industrial electroplating applications.

Aims and overview of the application bulletin

This bulletin provides step-by-step guidance for installing and configuring the 894 Professional CVS semiautomated system, optionally equipped with up to four 800 Dosino dosing units. It covers hardware setup, software configuration in viva, and operational routines for determining suppressor and brightener concentrations in plating solutions.

Methodology and instrumentation

The system combines electrochemical CVS analysis with automated reagent addition controlled by viva software:

• Instrumentation:
  
  • 894 Professional CVS semiautomated (or 884 VA semiautomated) with CVS electrode kit
  • viva 2.1 data acquisition and control software
  • Optional 800 Dosino units with 807 Dosing Modules (up to four units)
• Electrochemical method: Stripping voltammetry for suppressor (DT) and brightener (MLAT) analysis
• Automated dosing: VMS (volume masking solution), suppressor or plating bath sample, brightener and suppressor concentrates

System setup involves:

• Electrical connections of instrument and Dosinos to MSB ports
• Fluidic connections of tubing for reagent supply and waste
• Configuration of devices, electrodes (RDE, auxiliary, reference), dosing units and solutions within viva

Main results and discussion

The configured system performs:

• Suppressor determination by dilution titration (DT): automatic addition of VMS and suppressor concentrate, automated calibration or sample standard dosing, voltammetric measurement and evaluation
• Brightener determination by modified linear approximation technique (MLAT): sequential dosing of VMS, brightener concentrate, and sample additions with automated intercept and standard addition routines

Key operational findings:

• Automated dosing units ensure precise reagent delivery, minimizing operator variability
• viva software templates simplify method creation, requiring only minor adaptations for specific hardware and solution parameters
• Proper storage and maintenance of dosing cylinders and electrodes are essential to prevent blockages and ensure long-term reliability

Benefits and practical applications

The semiautomated CVS system offers:

• Higher throughput and consistent data quality for plating bath monitoring
• Reduced manual handling and associated errors
• Flexible software control for customized workflows and automatic reporting

This approach is well suited for industrial plating lines, research laboratories focusing on additive development, and QA/QC environments.

Future trends and possibilities

Emerging opportunities include integration of real-time process analytics, miniaturized microfluidic dosing modules, and AI-driven method optimization. Further enhancements may involve multi-analyte detection platforms and seamless integration with plant-wide process control systems.

Conclusion

The 894 Professional CVS semiautomated system, combined with viva software and 800 Dosino dosing units, delivers a robust solution for the automated determination of suppressor and brightener additives in electroplating baths. Its modular design and software templates support rapid deployment and high-precision analysis, reinforcing process control in plating operations.
