Abstract

Atomic absorption spectrometry plays an increasingly important role in analytical chemistry, particularly when the method is offered as a tool for the analysis of industrial samples. However, where the incidence of samples is exceptionally high, so is the discarding rate for lamps, which is an expensive business, particularly in a developing country, where such lamps can cost up to 5 times their original value in the United States or Europe, and take up to 6 months for delivery. In this laboratory we have opened, regenerated, and modified lamps which would otherwise have been discarded, and the purpose of this short communication is to report the procedure developed by us so that it may be of some benefit to other workers. Our procedure consists of the following.
