| Abstract: | The mathematical models are established for conventional atomic spectrometric signals by simulating experimental results with computer. The laboratory-made derivative measurement system is described. The mathematical models of derivative signals are developed for flame atomic absorption spectrometry(FAAS), flame atomic emission spectrometry(FAES), cold vapour atomic absorption spectrometry(CV-AAS), hydride generation-atomic absorption spectrometry(HG-AAS) and flow injection-flame atomic absorption spectrometry(FI-FAAS).The intensity of derivative signal is in direct relation to concentration of analyte with a good linearity . A theoretical principle is developed for derivative-FAAS, derivative-FAES, derivative-CV-AAS, derivative -HG-AAS and derivative-FI-FAAS. |
