| titleOfInvention | Ion chromatograph and sample injection method thereof |
| abstract | The invention provides an ion chromatograph and a sample introduction method thereof. The ion chromatograph includes: the sample injection needle comprises a needle tube, an ultrasonic sheet arranged on the surface of the tube wall of the needle tube and a metal film arranged on the surface of the ultrasonic sheet, in the hydrogen peroxide injection process, the decomposition of the hydrogen peroxide is catalyzed by the metal film to generate water and oxygen, the ultrasonic sheet continuously provides ultrasonic wave to hydrogen peroxide to play a role in degassing solution, removes oxygen generated during decomposition of the hydrogen peroxide, reduces the concentration of the oxygen in the hydrogen peroxide to the range of absolute safety and stable test performance of ion chromatograph detection, therefore, the hydrogen peroxide can not oxidize a system pipeline in the ion chromatograph in the sample introduction process, prevent oxygen from blocking an ion chromatographic column in the ion chromatograph, improve the detection stability and sensitivity, and ensure the quality of production raw materials and the consistency of process tests such as production process, monitoring and the like. |
