Residue method for common minor elements
Joseph Haffty
1960, Water Supply Paper 1540-A
A spectrographic method is described for the quantitative analysis of many minor elements in natural water. The excitation of the water residue using a direct-current arc provides a method for the detection of elements present in very low concentrations. The concentration of the elements is determined in percent of the...

The presence of the free water surface allows the possibility of departure from the relationship of resistance to the...
