The white test paper turns blue upon application of cobalt ions (Co2+). Interferences caused by iron or copper ions can be circumvented (see instructions for use supplied with the paper). Note: Non-destructive tests for the detection of cobalt in alloys are carried out as follows: apply 2 drops of acid solution (= 50 ml hydrogen peroxide 3 % + 7.5 ml o-phosphoric acid 85 % + 5 ml hydrochloric acid 37 %) to the degreased steel surface. After 30 to 60 seconds, absorb the liquid with the cobalt test paper. The presence of cobalt is indicated by a blue colour, the intensity of which varies according to the Co content.
