Additives Features.

Wide variety of VA techniques available.

Reliable, reproducible, and economical analyses, down to the ppt-level.

Reduces mercury waste when using Multi-Mode Mercury Electrode (MME) or Rotating Disk Electrode (RDE):.

Fully sealed MME Electrode contains only 6 ml of mercury and has a small capillary bore to ensure smaller, yet reproducible drops.

The electrode is sufficient for thousands of determinations.

RDE Electrode is interchangeable with the MME and is capable of achieving rotation speeds from 200 to 3000rpm.

Tips are available in gold, silver, platinum, graphite, and glassy carbon.

797 VA Computrace is a modern work station for voltammetric analysis.

Connected via a standard USB port, integrated Windows-based software controls the determination, data records and evaluates the measured data for the final result.

The easy to use software also includes pre-installed methods, with all necessary parameters, that are described in the Metrohm Application Bulletins and Metrohm Application Notes.

The newly integrated and designed Potentiostat/galvanostat offers the highest precision with reduced noise.

The well-designed Multi Mode Electrode (MME) and the ability to integrate a family of rotating disk electrodes (RDE) expands the capabilities of the 797 VA Computrace.

Important features include:.

Stripping Voltammetry for voltammetric trace analysis of metal ions and other substances.

CVS Cyclic Voltammetric Stripping for the determination or additives in plating solutions.

Exploratory Mode - the new standard for teaching in electrochemistry with the "Practical Voltammetry" Metrohm Monograph.

Powerful data handling with report generator.

More than 220 important analysis methods preinstalled.

Result in a wide variety of formats.

Integrated quality assurance with the GLP wizard, access rights for each user, and the automatic electrode test.

Simple and easy Windows 2000/XPPro program with clear user interface.

USB Connection.
