Background

An elemental instrument refers to an instrument that simultaneously or individually performs the analysis of several elements in a sample. Although the structures and the performances of various element analyzers are different, the element analyzers are designed based on the chromatographic principle. The working principle is that under the action of the composite catalyst, a sample is oxidized and combusted at high temperature to generate nitrogen, nitrogen oxide, carbon dioxide, sulfur dioxide and water, and the nitrogen, the carbon dioxide, the sulfur dioxide and the water enter a separation detection unit under the pushing of carrier gas. After the adsorption column adsorbs and retains the compounds which are not nitrogen elements, the nitrogen oxides are reduced into nitrogen and then are detected by a detector. The oxides of the other elements were separated and measured in the order of C, H, S by adsorption and desorption using an adsorption-desorption column. The presence of fluorine, phosphate or large heavy metal species in the sample can have a negative effect on the results of the analysis, whereas strong acids, bases or species that can cause explosive gases prohibit the use of elemental analyzers for the determination. Due to the mineral composition, crystal: the type structure is relatively complex, and in order to ensure the accuracy and stability of the measurement result, the sample particles must be sufficiently uniform when the element analyzer is used.
