Cadmium Measurement (Cd)

Carl Zeller Cadmium Analyser

The online analyser “Carl Zeller” from Seibold’s Composer analyser family continuously determines the cadmium concentration. Robust, proven and tested measurement technology affords high precision and sensitivity while keeping instrument complexity low. The result is a cost-efficient measurement. Easy and safe handling thanks to non-toxic reagents.


  • High accuracy
  • Easy handling
  • Minimal maintenance
  • Low cost per measurement
  • Robust design

The analyser adds a reagent specific for cadmium to the sample. If cadmium ions are present, a stable chelate complex forms between metal and reagent. This complex with its characteristic colour is detected precisely in the spectrophotometer. The intensity is directly proportional to the concentration of cadmium. The analyser takes care of regular automatic cleaning and calibration.
