Validation of the Volhard method for chloride determination in food

The aim of this paper is to compare the performance parameters of the Volhard method for chlorides determination obtained applying the bottom-up approach with those experimentally achieved. The method precision, trueness, detection and quantification limits and ruggedness are determined analysing various foods with different chloride contents. Otherwise, the measurement uncertainty is assessed applying the bottom-up approach using only pen and paper. The comparison between the performances established with both methods shows the validity of the metrological approach for volumetric procedures.
