Cross Sensitivity

The tube indicates metal chromates such as zinc or strontium chromate with about half the sensitivity.
CrIII compounds do not affect the indication.
Very high chromate concentrations lead to a rapid bleaching of the indication. Repeat the measurements with less strokes.

Additional Information

After carrying out the required 40 pump strokes, break the reagent ampoule. Then, transfer the liquid onto the indicating layer and carefully draw through it using the pump.
