The neutralization device is an online sample pre-processing device, which is mainly used for the detection of anions and cations in strong acid and alkali samples. Using electrodialysis and membrane exchange technology to neutralize the samples on the line to eliminate the interference of the sample matrix, which can replace the work of manual processing of the original pre-processing sample. And can be connected with the ion chromatograph, the sample processing, the installation is more simple. The number of neutralizations can be prepared according to the actual situation of the sample, and the pretreatment process of the sample can be realized by applying currents of different sizes. The neutralization module is connected to the sampler or ion chromatography electromagnetic six-way valve flow path, which can carry out on-line pre-processing operation and realize direct injection, fast analysis speed, high sensitivity, and can realize the pre-processing process of bulk reagents and other samples. The module can also be matched with an ultra-pure ion purifier to form an external module, to further purify the ion chromatography shower liquid with water, to meet the water requirements of the ion chromatograph.
