This article discusses the contribution of the tracer technique to the present state of development of trace element analysis. It reviews the use of radiotracers for testing the individual steps of the analytical process, especially with regard to the sources of systematic error. The major subjects considered are: sampling, storage and pretreatment of samples, sample decomposition, separation and preconcentration, and the measurement stage.
