Quantitative spectrographic analysis of corn leaf as a typical plant tissue has been carried out for several elements (Mg, Ca, Si), using a 1100-volt AC arc between carbon electrodes as a source. Tests have been made on various internal standards excitation conditions, etc., attempting to increase accuracy and reproducibility. Data and variations typical of the present status of the investigation are presented.
