Johnson Test Papers’ range of Qualitative Tests are ideal for the qualitative determination of specific ions and chemical compounds. If merely the presence of a compound is required without the detail of the concentration, then these tests will perform a single colour if that compound exceeds the detection amount.
These tests are highly efficient, require minimal effort and can provide a definitive qualitative answer if a sample contains compounds of interest. Some of these tests are for specific use only. Our tests are high quality, long life and are available for a comprehensive range of parameters as shown below.
