In participation of the laboratory on Proficiency Testing Scheme: Analysis of Proximates (Moisture, Fat, Protein, and Ash) and Minerals (Iron, Calcium, and Sodium) in Powdered Tonic Food Drink held by Food Nutrition Research Institute, Department of Science and Technology, Philippines (FNRI-DOST), Research Centre for Chemistry-LIPI conducted the estimation of uncertainty measurement in the determination of calcium (Ca) content in powdered tonic food drink using ion chromatography. The estimation of uncertainty measurement of laboratory participant of proficiency is needed for comparison with the standard deviation for proficiency assesment (σP
