Print PageTest paper allows the quick and easy detection of Cobalt (Co2+). For non-destructive testing of materials apply a drop of acid solution (50 ml hydrogen peroxide 3 % + 7.5 ml o-phosphoric acid 85 % + 5 ml hydrochloric acid 37 %) to the degreased surface. After 30-60 seconds absorb the liquid with the test paper. In the presence of cobalt a blue color appears. The intensity of the color varies according to the concentration. With this procedure Cobalt contents >0,5% are safely detected.
These test papers allow the determination of metal ions and metal containing compounds such as metal oxides. If you need to test for non-metal compounds including water detection, chloride, ammonium and many more, please see the range here.
They can be used to find out if compounds tested for are present in a quantity above a specific detection limit. Some of the described test papers can be used for non destructive testing of materials.
