| Abstract: | This article introduces the uncertainty assessment in measuring the arsenic content in sludge with the atomic fluorescence spectrometer. The factors of uncertainty during the measurement are analyzed and identified. It presents a relatively comprehensive assessment of measurement uncertainty. According to the standard uncertainty of least squares method fitting calculation working curve, the standard uncertainty resulted from less measurements is assessed with the range method. |
