Abstract
A method for determining concentration by means of atomic absorption spectroscopy, whereby the sample is supplied to a continuously operating atomizing device of an atomic absorption spectrometer by flow injection technique and generates a transient output signal of the atomic absorption spectrometer, comprises the method steps of supplying a calibration sample with a known concentration of the looked-for element to an atomic absorption spectrometer by flow injection technique, the concentration of the element looked-for in this sample being in a range of minimum standard deviation; storing the obtained transient calibration signal; supplying a sample which is to be analyzed and has an unknown concentration of the looked-for element to the atomic absorption spectrometer by flow injection technique and measuring a transient sample signal; forming signal ratios of the sample signal and the calibration signal at mutually corresponding predetermined moments of time; and determining the concentration of the looked-for element in the sample which is to be analyzed from these signal ratios.
