Samples are placed in a plasma reactor through which oxygen is passed. The R-F field within the reactor converts the molecular oxygen into an active species, i.e. atomic oxygen. Low-temperature oxidation results with the consequent removal of carbon, hydrogen and nitrogen as volatile oxides, and the retention of most metallic ions. This technique has been successfully used for the past year to effectively destroy organic matrix in combustible samples without excessive loss of mineral content and to improve analyses based on atomic absorption, emission spectroscopy and conventional 'wet' methods"--Abstract, p. i. |
