A collaborative study has been conducted on a modification of a previously reported automated method for phosphorus in meat products. Samples were dissolved in 1 + 1 sulfuric acid, cooled to room temperature, and presented to an AutoAnalyzer system. Digestion, dilution, and colorimetric measurement of phosphorus content were performed automatically. Six collaborators participated in the study, analyzing 8 different samples in duplicate. Results of the study were good, with an average range of 0.012% P, average standard deviation of ±0.0047, and average coefficient of variation of 2.32%. The method is recommended for adoption as official first action.
