Abstract

Abstract

The uncertainty of phosphate measurement in offshore water in the East China Sea was studied with the general method.By analyzing the effective factors of measurement uncertainty,such as the specific measurement environment,the standard materials used,the sampling volume,mole quality,etc.,the standard uncertainty,the combined standard uncertainty and the extended uncertainty of phosphate measurement were estimated.The results show that the specific measurement environment is the main fluencing factor of measurement uncertainty of phosphate,and the relative combined standard uncertainty of phosphate in the offshore water in the East China Sea is about 0.067.
