Abstract

Spectrochemical techniques often offer relatively rapid method of making simultaneous determination of certain elements in plant tissues. The feasibility of using a flame as a source of excitation with the medium cornu spectrograph was explored. The effect of several variation, such as, oxygen and acetylene pressures, the spectrograph slit width, the distance of the source from the slit, and the time of exposures was studied. Although the efforts exerted to determine the optimum operating conditions with the use of a flame burner seemed futile, an alternative method using a fisher todd spectranal with an underwater spark source looked promising. A number of elements were determined both qualitatively and semi-quantitatively. The range of element concentrations detected was from 0.01 to 3.0 mg./g. of sample
