AI Technical Summary

Problems solved by technology

This is a tedious work process that will bring hidden dangers to the inaccuracy of data
If you are not careful, you will not be able to make a scientific, comprehensive and accurate analysis of the analysis and transmission of the standard value
The above state cannot meet the needs of analysis and testing in many technical fields in my country
At present, there is no such reference material in China, and there is no report of this type of reference material abroad.

Abstract

The present invention relates to the technical field of measuring and testing standard value transmission, in particular to a plasma emission spectrum analysis mixed ion standard widely used in the research and monitoring of metallurgy, geology, environmental protection, medicine and health, agriculture, chemical industry, food and other departments Substance (standard sample). Its 1L capacity contains 1.00-10.00mg of gold (Au), 1.00-10.00mg of iridium (Ir), 1.00-10.00mg of palladium (Pd), 1.00-10.00mg of platinum (Pt), and 1.00-10.00mg of rhodium (Rh). , antimony (Sb) 1.00-10.00mg, tin (Sn) 1.00-10.00mg, tellurium (Te) 1.00-10.00mg, dissolving agent 100mL, and the rest is basic body (mL). The invention can not only provide traceable substances for daily emission spectrum analysis and testing, but also broaden the technical basis for national metrological verification work, and at the same time make up for the gaps in the field of national standard substances in the field of mixed metal ion standard substances.

Description

technical field [0001] The present invention relates to the technical field of measuring and testing standard value transmission, in particular to a plasma emission spectrum analysis mixed ion standard widely used in the research and monitoring of metallurgy, geology, environmental protection, medicine and health, agriculture, chemical industry, food and other departments Substance (standard sample). Background technique [0002] In metallurgy, geology, environmental protection, medicine and health and other industries, emission spectrum analysis has been used as a routine analysis method. Emission spectrum analysis is a relative measurement method, and the source must be traced through the standard substance of the corresponding element during the whole analysis process. At present, my country is quite short of standard materials for national calibration of mixed metal ions, which is reflected in two aspects: (1) there are few types of mixed metal elements; (2) the concent...
