| Abstract: | A volume-reduction technique is described for the X-ray spectrographic analysis of the micronutrient elements manganese, iron, and zinc in plant tissues. This simple technique is believed to minimise inter-element effects and utilises dilution by volume instead of by weight, thus avoiding intimate mixing of sample and diluent. The method has particular advantages for the analysis of manganese and iron when they occur in plant tissues in concentrations large enough for inter-element effects to be serious. |
