Abstract

The invention discloses an element form analyzer in the technical field of analyzers. The element form analyzer comprises a sampling device, a valence state separation chromatography device, a DC positive and negative valence state ionophortic separation device, a relative state intervention device, an electrochemical hydrogenation device, a gas state hydride stability deviation transition device,an atomic fluorescence spectrometer and a waste liquid treatment device. Sample pretreatment is conducted in a high-performance liquid chromatography-ionophortic valence state separation-hydrogenation-hydride deviation mode, then atomic fluorescence spectrum detection is conducted, the problems that an existing element analyzer is poor in repeatability, low in sensitivity and not accurate in formdata are solved, and the complicated sample pretreatment process is avoided.

Description

technical field [0001] The invention relates to an analysis instrument, in particular to an element form analyzer. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. Heavy metals can accumulate in the human body, and once they exceed the tolerance limit of the human body, they will be poisoned and cause great harm to the body. The degree of harm depends on the concentration and chemical form of heavy metals. The toxicity of heavy metals with the same concentration varies greatly in different forms. Therefore, it is necessary to analyze heavy metal elements in different forms. [0003] At present, in the spectroscopic detection application of speciation analysis, cumbersome sample pretreatment process is often required, and the relative ions, substituents, and functional groups in the relative state of the substance or pretreatment reagent cannot be eliminated or shielded, thereby interfering with t...
