Abstract：Every year，increasing number of the laboratories using OES (Optical Emission Spectroscopy) spectrometers gets accredited according to ISO 17025 The compliance with ISO 17025 has elevated the importance of estimating and reporting measurement uncertainty The Guide to the expression of uncertainty in measurement (GUM) provides guidelines for conducting an uncertainty analysis Unfortunately, the implementation of these guidelines can be a daunting task, especially if one is not familiar with the necessary mathematical and statistical concepts Consequently, testing and calibration personnel must often find offtheshelf tools that meet their analysis requirementsThe paper presents the way that Thermo Fisher has implemented in its analytical software the calculation of the measurement uncertainty It also describes an application based on the knowledge of the uncertainty in the goal to calculate the product conformance probability
