This article describes the concept of controlling and correcting interference resulting from flame instability and sample reduction in absorption atomic spectrometry with flame atomization. Using popular laboratory spectrometers, which enable simultaneous or fast sequential measurements of many elements in the course of a single analysis, methods of controlling and correcting problems with instruments (e.g. reduction of sample flow) that directly affect the recorded analytical signal were elaborated.
