Metrohm has unveiled its scTRACE Gold sensor designed for the straightforward voltammetric determination of arsenic in water.
The scTRACE Gold is plugged in the electrode shaft and as there is no preconditioning required, users can start measuring immediately after.
Metrohm claims analysis time per sample is approximately 10 minutes only and detection limit is well below the 10 µg/L stipulated by latest legislation in the US and the EU.
The scTRACE Gold combines all three of the electrodes needed for the measurement in one sensor.
Screen printing makes it very affordable, which means that regular replacements are not a problem. This ensures reliable results at all times and does not require any maintenance.
A further benefit of voltammetric measurements with the scTRACE Gold is the ability to discriminate between different oxidation states of arsenic, notably the highly toxic As(III) and the less toxic As(V).
Additionally, the scTRACE Gold can be used with any Metrohm voltammetry measuring stand.
