Arsenic Measurement (As)

Wilhelm Kienzl Arsenic Analyser

The online analyser “Wilhelm Kienzl” from Seibold’s Composer analyser family continuously determines the arsenic concentration. Arsenic has a number of industrial applications. However, if certain geological conditions are met, arsenic from natural sources can be found in ground water as well. The robust, proven and tested measurement technology determines arsenic with 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.

Advantages

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

Method

The analyser adds a reagent specific for arsenic to the sample. If arsenic 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 arsenic. The analyser takes care of regular automatic cleaning and calibration.

Applications

  • Drinking water
  • Process water (semiconductors)
  • Ground water monitoring
  • Landfill water
