Metrohm^® 797 VA Computrace for trace analysis and metal speciation

The 797 VA Computrace can carry out trace metal analyses with the same or better sensitivity for a fraction of the cost of an AAS or ICP instrument. With low operational costs, small amounts of reagents and a small footprint, the 797 VA Computrace makes trace analysis easy and fast using the standard addition method typically used in these analyses with detection limits down to ppt.

Metal speciation

In addition, total metal concentration and speciation can be determined with the computer-controlled software system. Curve evaluation and automated dispensing options make the 797 VA Computrace system a valuable tool to distinguish the different oxidation stages of metal ions or to differentiate between free and bound metal ions as well as to specify the biological availability of heavy metals in environmental analysis.

Environmental analysis

The 797 VA Computrace makes voltammetry an essential tool for environmental analysis. Comparable insights can only be gained by spectroscopy after complicated separation of the metal species. Its compact size means that the 797 VA Computrace system can also be used in mobile laboratories. Samples with high ionic concentration are no problem for voltammetry.

Organics and anions

The 797 VA Computrace can be used to determine trace quantities of various organic compounds by voltammetry in organic chemistry and pharmaceuticals. Some special anions, such as sulfide, nitrite and nitrate, can also be determined by voltammetry.
