Application of Excel in uncertainty evaluation of chemical measurement |
|
|
Abstract The evaluation of measurement uncertainty involves the calculation of least square method, which is often more complex. With the popularization of electronic original records in measurement work, the calculation function of Excel software is combined with electronic original records, which is applied to the evaluation of uncertainty, realizing automatic data processing and greatly improving the work efficiency of measurement and detection, At the same time, it can effectively improve the accuracy of data. Through two examples, the evaluation templates of uncertainty of ICP and ICP-MS detection limit measurement results calculated by Excel are established. The results show that it has strong practicability for the measurement institutions that need to give the uncertainty of measurement results each time.
