894 Professional CVS – Cyclic Voltammetric Stripping for the determination of additives in electroplating baths

Product catalog summary
Overview: The document provides an in-depth look at the 894 Professional CVS system, which is used for determining organic additives in electroplating baths through cyclic voltammetric stripping (CVS). It emphasizes the system's flexibility, convenience, and security features, enhanced by the viva software.
Specifications: The 894 Professional CVS is a modular system that can be expanded with additional units such as dosing devices and pumps. It includes a built-in calibrator for precision and an exchangeable measuring head for quick method changes. The system is compact, measuring 18.8 cm × 45.2 cm, and connects to a computer via USB.
Procedures: The document describes several techniques for additive determination, including:
  • Suppressor determination using Dilution Titration (DT).
  • Brightener determination using Modified Linear Approximation Technique (MLAT) and Linear Approximation Technique (LAT).
  • Leveler determination using Response Curve (RC).
Automation Options: The system can be configured for manual, semi-automated, or fully automated operation, with options for automatic dosing and rinsing. Models MVA-20 and MVA-21 offer high sample throughput capabilities.
Software Features: The viva software facilitates task-focused method programming, data management, and security. It supports custom method creation, automatic calculations, and various report generation options. A control chart function is included for setting warning and intervention limits.
Data Management and Security: The viva software ensures data security with user administration and password protection. It allows data export to QM systems or LIMS and supports central data management in a client-server setup.
Benefits: The 894 Professional CVS system provides high accuracy, reliability, and cost-effectiveness by minimizing reagent use and analysis time. It is supported by over a decade of Metrohm's experience in CVS analysis.
Data Management and Maintenance: The viva software centralizes methods and determinations on a server, enabling data access and editing from any PC with a viva client. It complies with Good Laboratory Practice (GLP) by monitoring maintenance intervals and issuing alerts if component lifespans are exceeded. Regular database backups ensure data security.
Technical Specifications: The 894 Professional CVS is a voltammetric measurement stand with an integrated potentiostat and galvanostat. Key specifications include dimensions (188 mm width, 322 mm height, 452 mm depth), weight (7.4 kg without accessories), and various measurement ranges for potential and current. A PC with Windows OS and a stable network connection is required for operation.
Ordering Information: The document details various configurations and accessories for the 894 Professional CVS, including manual, partially automated, and fully automated systems for different sample series sizes. It also lists compatible electrode kits and temperature sensors.
Additional Information: More details about the viva software version and licenses can be found on the Metrohm website.
