Online voltammetric polarographTechnical Specifications:
Analysis of Total Heavy Metal Content
Compared to AAS or ICP-AES, the voltammetric polarograph can perform the same or even more sensitive metal analysis. And the consumption of reagents is minimal, requiring only a small amount of high-purity nitrogen. No need for expensive combustible gases, no need for special gas experimental facilities and ventilation equipment, and no need for expensive elemental lamps.

morphological analysis
Spectroscopy can only detect the total metal content. Voltammetry can distinguish between metal ions in different valence states, bonded states, and free metal ions. This can evaluate the bioavailability and heavy metal toxicity, making it a necessary technique for environmental analysis. Spectral analysis can only be used for comparative evaluation of complex metal species after separation.

No high salt interference
The voltammetric polarograph does not have the problem of high salt matrix interference. This means that voltammetry can analyze the following substances:
Water, wastewater, and seawater
Salt, high-purity chemical reagents
Electroplating solution
