The electro-spectrum sample preparation device is connected with the washing sampling device; ions obtained by electrolyzing a solid sample can enter the washing sampling device with the washing liquid together; the washing sampling device is connected with the chromatographic analysis device; the liquid sample can be inputted into the chromatographic analysis device to analyse. The utility model has the functions of sample preparation and analysis, and can quantificationally measure a plurality of ions of solid matters only by installing the solid sample simultaneously. The utility model can eliminate the cockamamie process of sample preparation, and the analytical precision can reach to 2%.
Description
The utility model belongs to the ion chromatography field, relates to a kind of instrument that is used for directly analyzing solid sample.
Though middle nineteen seventies occurs and the development chromatography of ions and support equipment-ion chromatograph quantitative test accuracy height so far, but only be applicable to the analysis of liquor sample, therefore for solid matters such as iron and steel, alloy, ores, could analyze after must being prepared into liquor sample.The liquor sample preparation of solid matter, the existing conventional method needs grinder buffing, drilling machine drilling, sample weighing, chemical treatment, not only operation various, expend time in and chemical reagent, and prepared sample disturbs when ion chromatography greatly, causes separation detection very difficult.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electricity spectrum-ion chromatograph is provided, and it integrates sample preparation, stratographic analysis function, the different kinds of ions in the solid matter of quantitative measurement simultaneously.
The purpose of this utility model is achieved in that the characteristics according to solid sample, and the electrography and the chromatography of ions are united use, utilizes the principle sample preparation of electrography, utilizes chromatographic principle analysis.Under above-mentioned design philosophy instructs, electricity provided by the utility model spectrum-chromatograph comprises that electricity composes sampling device, washs sampling device and chromatographic analysis device, electricity is composed sampling device and is linked to each other with the washing sampling device, the ion that its electrolysis solid sample is obtained enters the washing sampling device with cleansing solution, the washing sampling device links to each other with chromatographic analysis device, and aqueous token import chromatographic analysis device is analyzed.
The utlity model has following advantage:
1, integrates sample preparation, analytic function, only need install solid sample and just can analyze.
2, sample preparation speed is fast, the about preparation that just can finish liquor sample in about 1 minute.
3, the different kinds of ions in the solid matter of quantitative measurement simultaneously.
4, analytical precision height, to test buttons such as iron and steel, precision can reach 2%.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of the electricity spectrum-ion chromatograph that proposes according to the utility model;
