Rare earth ore sample sequential ionization analysis instrument

Abstract

The invention discloses a rare earth ore sample sequential ionization analysis instrument. The instrument comprises a sequential soft ionization device and a mass spectrum detection device. The sequential soft ionization device comprises a reagent quantitative adding and mixing system, a micro liquid layout conveying system, a microscopic morphology analysis system, a micro sample pool and interface system, a field energy coupling and regulation and control system, a special efficient ionization system, a time sequence triggering and intelligent control system and a supporting and connecting system, the eight systems are scientifically arranged and compactly installed on the supporting and connecting system, and the other systems work under the control of the time sequence triggering and intelligent control system, so that all the systems are assisted in time and space. According to the method, molecular structures (M), abundance contents (A) and spatial distribution (D) of different components of an ore sample at a molecular level can be obtained without complex sample pretreatment conditions.

Description

technical field [0001] The invention relates to the technical field of analysis equipment, in particular to a sequential ionization analysis instrument for rare earth ore samples. Background technique [0002] Because of their unique optical, electrical and magnetic properties, rare earth elements have important applications in many high-tech industries and are an important strategic resource. [0003] Rare earth raw ores are mixed and stacked together by various components through physical and / or chemical effects of different strengths, among which rare earth elements occur in various forms. [0004] Due to the special complexity of raw rare earth ores, it is generally necessary to use sample pretreatment steps to separate the analyte elements in the sample before detection. Commonly used speciation analysis methods mainly include BCR method, Tessier method and improved methods based on this method. In these methods, rare earth ore samples usually need to go through a mult...

Problems solved by technology

However, only by increasing the excitation energy, the total amount of a certain element is determined, and it cannot effectively distinguish between different types of metal elements in the sample and between metal elements, metal salts and metal oxides.

[0006] Judging from the current literature research situation, no principle conception that can directly analyze the different occurrence forms of elements in ore samples has been found at home and abroad, nor has the design or development of similar instruments been found.
