The method consists of heating a sample to 360–410 °C with concentrated sulfuric acid (H2SO4), which decomposes ("digests" or "destructs") the organic sample by oxidation to liberate the reduced nitrogen as ammonium sulfate. Hot concentrated sulfuric acid oxidizes carbon (as bituminous coal) and sulfur (see sulfuric acid's reactions with carbon): C + 2 H2SO4 → CO2 + 2 SO2 + 2 H2O S + 2 H2SO4 → 3 SO2 + 2 H2O
