摘要：

The development of two-stage control systems is of great interest when a large number of samples are analysed in order to check that they fulfil certain requirements. If the first stage is carried out using an inexpensive method with a high throughput which makes it possible to filter out the majority of the samples that fulfil the requirements, the procedure is not only less time-consuming but also more economical. Direct determination of metals in solid samples by graphite furnace atomic absorption spectrometry (GFAAS) appears, in principle, to be a suitable analytical technique for screening purposes since it provides sufficiently reliable results in a reasonably short time. In this paper it is applied with satisfactory results to antimony content control in a PVC sample. (C) 1998 Elsevier Science B.V. All rights reserved.
