Metrohm has introduced the 797 VA Computrace, which can carry out trace metal analyses with the same or better sensitivity as an AAS or ICP instrument.
The 797 VA Computrace features low operational costs, small amounts of reagents and a small footprint.
It makes trace analysis easy and fast using the standard addition method typically used in these analyses, with detection limits down to PPT.
It can also determine total metal concentration and speciation.
Curve evaluation and automated dispensing options make the 797 VA Computrace system suitable for distinguishing the different oxidation stages of metal ions or for differentiating between free and bound metal ions and for specifying the biological availability of heavy metals in 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.
The 797 VA Computrace can 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.
