Abstract
An approximate solution of the absolute method of atomic fluorescence analysis has been considered with regard to the development of hybrid methods of analysis, which includes sample pre-treatment, isolation, separation and pre-concentration of analyte elements in the form of individual volatile compounds and final determination with the use of gas-phase atomisation. Each method discussed allows the analysis of a wide range of samples by use of a spectrometer that is calibrated on pure compounds of the analyte elements or on simple synthetic standards, without the need for standard reference materials. Such methods of analysis are applicable to the determination of trace elements in many materials, with particular emphasis on environmental samples.
