PURPOSE:To remove interference component elements in a sample, by guiding the sample to the inside of a cation exchange film tube, whose outside is filled with a specified removing liquid, and exchanging the ion exchanging group in the tube by the cation in the sample. CONSTITUTION:When a pump 4 is driven, a sample in a bath 1 passes cation exchange film tubes 2 and 2' and flows out of a capillary 6 of an outlet part 5. A spectrochemical analysis apparatus utilizing atomic light emission is provided in this way. When the sample passes the cation exchange film tube 2' in a bath 3, the sample is contacted with a removing liquid in the bath 3. The ion exchange group in the cation exchange film 2' is exchanged by the cation in the sample. Even if interference component elements are present in the sample, the elements are removed and are not included in the liquid, which flows out of the capillary 6. Therefore, even if the interference component elements are included in the sample, the element to be measured can be accurately measured. |
