Тезис

This document specifies the practical use of the fundamental concepts in ISO 11843 in case of the background noise predominance in instrumental analysis.

This document specifies basic methods to

     extract the stochastic properties of the background noise,

     use the stochastic properties to estimate the SD or CV of the response variable, and

     calculate the minimum detectable value based on the SD or CV obtained above.

The methods described in this document are useful for checking the detection of a certain substance by various types of measurement equipment in which the background noise of the instrumental output predominates over the other sources of measurement uncertainty. Feasible choices are visible and ultraviolet absorption spectrometry, atomic absorption spectrometry, atomic fluorescence spectrometry, luminescence spectrometry, liquid chromatography and gas chromatography.
