This test paper shows potassium as orange-red spots on a light yellow background. Rubidium, cesium and thallium(I) also produce orange-red color reactions. Excess of sodium and heavy metal ions reduce sensitivity. Larger amounts of ammonium ions cause interfering discolorations. In the instructions for use, which are supplied with the paper, a special method is provided to circumvent any of these interferences. Limit of sensitivity: 250 mg/l K + Instruction Sheet (For semi-quantitative determination see Ref 91316 Quantofix Potassium)
