The VisuPAsS Visual Portable Arsenic System
Designed for the most challenging environments where electronic detection is not required or desirable and a lower cost alternative is required.
Using the well-established Gutzeit method the system operates by converting all
Arsenic in the sample to Arsine gas and detecting the gas produced quantitatively
using a unique three-stage filter. The filter ensures all Arsine is ‘seen’ by the detector
and also prevents excess Arsine or Hydrogen Sulphide being released during
the 20 minute reaction time. Once the reaction is complete the concentration of Arsenic is quickly assessed using a colour chart ranged from 10 to 500 μg/l Arsenic.
Each kit contains sufficient reagents and consumables for 200 tests packaged in a
robust field carry case.
