| 摘要 |
A more efficient method for combustion or oxidation of samples containing nitrogen, phosphorus and/or sulfur to their corresponding oxides is disclosed, where method uses multi-staged addition of an oxidizing agent to enhance oxidation and liberation of nitrogen, phosphorus and/or sulfur oxides for subsequent detection. The method of the present invention allows for the injection of larger samples or the introduction of a greater amount of sample per unit of time which results in a larger amount of analyte being delivered to the detector per unit of time, thereby improving detection limits and detection efficiency.
