| Popis: | The five stepwise purification of extracts and final precipitation of silver phosphate (A1–A5) are described. The first two steps (A1 and A2) are removing organic matter and are concentrating the phosphate in the extract by reducing the volume. Certain cations could interfere with the precipitation of silver phosphate and are removed in step A3. Silver chloride, which, if not removed, could co-precipitate with silver phosphate, is removed in step A4. The final analyte is then precipitated in step A5. The filtration steps can be quite tedious, using vacuum filtration equipment is therefore recommended. Following step A5, the silver phosphate samples need to be weighed in for the measurement with a thermal conversion elemental analyser (TC/EA) coupled to a continuous-flow isotope-ratio mass spectrometer (IRMS).
