Novel elements for the analysis of aqueous liquids which may contain gentisic acid as an interferent are described. Interference of gentisic acid with the analytical test reactions is reduced by using an organic solvent that dissolves the indicator composition but does not preferentially partition gentisic acid into itself from aqueous liquids.
