Convert oxides to elements (and vice versa)
Enter the list of element (or oxide) to recalculate as oxide (or element).
The input can contain more than one analysis with the same series of oxide/element.
Aluminosilicate, SiO2, Al2O3, FeO
Sample1, 36.10, 62.85, 1.87
Sample2, 35.46, 63.56, 0.98
WARNING: if entering element with oxygen wt-%, default oxide will be loaded unless you specify the oxidation state (e.g. Fe3+, Cu+).
When converting element weight-% to oxide weight-%, you can force recalculating the equivalent oxygen content based on the selected oxidation state (see next step).
Oxygen content is automatically recalculated when converting oxide weight-% to element weight-%.
