Summary:A pre-treatment process involving 5% NaOCl (<24 hr) followed by Ag3PO4 (15-20 min) has been developed for the isotopic analysis of calcite- or dolomite-bearing samples associated with organic matter and sulphide minerals. This treatment purifies the CO2 gas of contaminating S-bearing organic species and H2S which are generated during the reaction of the sample with phosphoric acid. [R.A.H.]
