Abstract

The invention discloses an automatic system for analysis pretreatment on nitrate nitrogen and oxygen isotope samples. The automatic system comprises a support base frame, a worktable, a support frame,a liquid adding box, a feeding mechanism, a plurality of shakers and a three-dimensional mechanical arm. The worktable is fixed to the support base frame. The shakers are fixed to the worktable. Thesupport frame is fixed on the periphery of the support base frame. The feeding mechanism is fixed to the support frame. The feeding mechanism is located above the worktable. The liquid adding box is fixed to one side of the support base frame. The three-dimensional mechanical arm is installed on the worktable. The three-dimensional mechanical arm is provided with a needle sleeve rod. A liquid supply port of the liquid adding box is communicated with a liquid inlet of the needle sleeve rod through a hose. The structure can greatly improve the efficiency of analysis pretreatment on the nitrate nitrogen and oxygen isotope samples and can prevent the health hazard and safety hazard to the operator.

Description

technical field [0001] The invention relates to the field of analysis of nitrate nitrogen and oxygen isotope samples, in particular to an automatic system applied to the analysis pretreatment of nitrate nitrogen and oxygen isotope samples. Background technique [0002] The pretreatment of nitrate nitrogen and oxygen isotope sample analysis mainly includes several steps such as sample dilution, pH value adjustment, reduction of copper-plated cadmium particles, and chemical conversion. Sample dilution is used to reduce the concentration of nitrate ions in the sample to meet the test requirements. , the pH value adjustment is used to adjust the pH value of the sample to the acidity and alkalinity that is beneficial to the reaction, the reduction of copper-plated cadmium particles is used to reduce the nitrate ion in the sample solution to nitrite ion, and the chemical conversion is used to convert the nitrite ion In the above steps, on the one hand, the dilution of the sample a...
