A very good quality machine, suitable for carrying out highly technical analyses.
Rating: 3.3

  • Application Area:Brightener and suppressor analysis in copper electroplating solutions

"For our application, the product is good at it's job. Whilst our current software is not the most up-to-date issue, it is still easy to operate, although understanding the reasons or procedures behind why certain settings have to be "like that" does take a little time to comprehend. Overall, the machine is very good, with any problems mostly to do with the material(s) that we are trying to analyse. Whilst the equipment is rather pricey, it is of excellent quality, with any failures due to age-related wear-and-tear, rather than faults with the apparatus. The documentation provided by Metrohm is easy to follow, and logical in its approach."

A robust, easy to use instrument even in the hands of chemistry students.
Rating: 5.0

  • Application Area:Water analysis for trace metals and juice analysis for Vitamin C in student analytic lab

"The VA 797 Computrace serves to introduce the analytical chemistry methods of polarography and voltammetry to 4th semester chemistry students. The students analyze a tap water sample for the concentration of zinc, copper, lead and cadmium ions and a juice sample for the concentration of vitamin C. In the summer semester about 50 students work with the instrument over 5-6 weeks, in the winter semester another ~50 students use the instrument over 5-6 weeks. The students are given a handout with instructions how to use the instrument. The instrument has been in service now for about 8 years. So far, we've had no major damage done to the instrument and no major failure. The mercury drop electrode is, of course, regularly serviced by a staff technician. We obtain very reliable data from the instrument as verified by the large number of experiments done on easily comparable samples. The VA 797 Computrace is easy to operate and robust as demonstrated with the lab course. We had no problems giving the instrument into the hands of students. Once or twice in the 8 years of service we had to contact Metrohm service which responded fast and we were able to solve the problem without a visit. Outside of the time of the lab course the instrument is available for metal analysis in aqueous solutions."

Just what we needed .
Rating: 4.0

  • Application Area:Thiourea in copper electrolyte solution

"When replacing the outdated equipment for thiourea analysis, the best option was the VA 797. This instrument was accurate and flexible enough for our processes. We use it on a daily basis for accurate results in the ppm range. The only issues we have is plugging of the capillary tube. But, this has to do with our solutions we run on the instrument. We have had a few service calls and Metrohm took care of the problem in a timely manor. Parts and supplies are easily available."

  • Application Area:Impurities.

"This is a great product and is easy to use. It is easy to clean and the finish on the instrument resists corrosion. All parts are easy to exchange in the unit. The software is very user friendly for all technicians. Metrohm customer support has been great and has knowledgeable people to troubleshoot with when called on. The price of the instrument is fair and the instrument seems to be hardy for the lab environment."

The versatile instrument for voltammetry

797 VA Computrace is a modern voltammetric work station connected to the PC via a USB port. The complementary PC software controls the determination, records and evaluates the measured data. Thanks to the sophisticated program design the operation is unbeatably simple. All the methods that are described in the Metrohm Application Bulletins and Metrohm Application Notes are already preinstalled. The integrated new designed potentiostat with galvanostat guarantees highest precision with reduced noise. The well-proven Multi Mode Electrode (MME) as well as rotating disk electrodes (RDE) from different materials are available as working electrodes, of course.

The most important applications

  • Stripping Voltammetry: Voltammetric trace analysis of metal ions and other substances
  • CVS: Cyclic Voltammetric Stripping for the determination or additives in plating solutions
  • Exploratory: The Metrohm concept for teaching in electrochemistry
