ADI2045VA Process Analyzer
Metrohm Process Analytics
The ADI 2045VA analyzer is based on the principle of Voltammetric Analysis. The analytical heart of the analyzer is the Metrohm 797 Computrace with Multi Mode Electrode (MME) or Rotating Disk Electrode (RDE) sensor options depending on the application. For online control of water and wastewater quality and industrial mining processes the analyzer is used to determine low concentrations of multiple heavy metals e.g. Cu, Zn, Cd, Pb, Ni and Co. The concentration range can vary from ppm down to ppb/ppt trace detection.
The 2045VA can be equipped with a UV or thermal digester module to release metals if they are bound in (organic) compounds. In electroplating baths for the production of PCBs and semiconductors the analyzer utilizes CVS/CPVS voltammetric stripping methods.
Typical applications are for organic additives such as brighteners, levelers and suppressors. Quantification of these bath additives require different calibration methods and have all been implemented in the analyzer software.
