Determination of the 13c of Dissolved Inorganic Carbon in Water - Bog - Paperback
The purpose of the Reston Stable Isotope Laboratory (RSIL) lab code 1710 is to present a method to determine the 13C of dissolved inorganic carbon (DIC) of water. The DIC of water is precipitated using ammoniacal strontium chloride (SrCl2) solution to form strontium carbonate (SrCO3). The 13C is analyzed by reacting SrCO3 with 100-percent phosphoric acid (H3PO4) to liberate carbon quantitatively as carbon dioxide (CO2), which is collected, purified by vacuum sublimation, and analyzed by dual inlet..
