FerroVer Iron Reagent converts all soluble iron and most insoluble forms of iron
in the sample to soluble ferrous iron. The ferrous iron reacts with the
1,10 phenanthroline indicator in the reagent to form an orange color in
proportion to the iron concentration. Test results are measured at 510 nm.
