Sulfuric Acid can be cooked down to dryness in quartz
beakers to minimize interferences. H2SO4 interferences
will be present after the cook down in Ti,Cu, and Zn.
Ti47, Cu63, and Zn68 are isotopes used in this cook
down method without interference. A direct dilution
prep is needed to analyze B, As, and Au. These
elements are volatilized during cook down preparation.
The cook down method achieves ppt levels.
