The Error Analysis and Modeling of Automatic Chemistry Analyzer

In order to find out the relationships among the four error sources,namely,locating error,noises of optics system,sampling error and temperature fluctuations,and the accuracy of the instrument,the TP test is taken as a clue,each relationship of them is analyzed and it is found that the affection of the locating error is too small and can be ignored.The total error model and the model of the allowed noise of the optics system of the instrument are established in this paper.
