Problems solved by technology

[0002] For the testing of aluminum-copper alloy materials, the national standard chemical analysis method is currently used. The analysis of each element needs to weigh the sample separately, and use different dissolution methods to dissolve the sample. More than a dozen reagents are used to complete the determination of one component. , the analysis time is long, the efficiency is low, and the detection of all the components to be tested cannot be completed at the same time

Embodiment 1

[0038] To analyze the aluminum bronze QAL10-3-1.5 sample numbered H9-1, the test steps are as follows:

[0039] 1. Flush the excitation chamber with an argon flow rate of 8L / min for 10s,

[0040] 2. From the standard sample QAl9-2, select samples 925 and 929 with the highest and lowest content of Al and Mn elements, and samples 920 and 924 with the highest and lowest content of Fe elements to excite and standardize the working curve respectively. See Table 1 for the value of the normalization coefficient α.
