Abstract
A spectrochemical method has been evolved for the determination of trace elements to soil and plants with the objects of reducing the micro photometry involved in the variable internal standard method and of increasing the throughput of samples. A 3-step filter replaces the step sector and evaluation is achieved from an emulsion calibration curve prepared from step filter data using the Rcspektra Calculator. The errors involved in cert.in stages .re studied, and the resulting method shows accuracy comparable to the original.
