METHODS FOR SAMPLING AND INORGANIC ANALYSIS OF COAL
U.S. Geological Survey Bulletin 1823

Edited by D.W. Golightly and F.O. Simon

Table 9. Concentrations of 40 elements in multiple-element standards used for the analysis of coal (ug/g, unless percent indicated).

[Sulfur was not included because it was below the detection limit for all these standards, and elemental sulfur was used as a standard.]
