Does the spectrometer for detecting metal composition have any impact on the results of detecting al

I think there is a certain impact, the electrode brush electrode is difficult to brush clean, and the electrode brush will also remain on the residue of the previous zinc measurement, so, if the aluminum profile is directly transferred, the content of zinc in the aluminum will have a little impact, and the others will be less, some users who use the spectrometer will require the spectrometer manufacturer to match the spark plate, electrode brush, electrode, etc. when using multi-matrix instruments, and use a set for each substrate, and do spark table cleaning and corresponding replacement when replacing the substrate. To ensure that the impact of the process of replacing the measurement material is eliminated as much as possible, of course, this influence can be ignored when making alloys, and it will feel more obvious when doing pure metals.

There will be no effect, the impact caused by the conversion matrix of the spectrometer is mainly due to the residue after the previous excitation falls in the excitation table and causes the secondary excitation pollution, so the operation of the spectrometer requires that each excitation should be cleaned with an electrode brush, and there is argon purging in the excitation stage, which can also play a certain role.

And last night, after the zinc alloy, you need to do the type calibration of the aluminum alloy first, so there should be no problem when the aluminum alloy is actually tested.

Generally, after making a material, brush it with an electrode brush, and it will not have any effect.

Summary. Hello! In general, there are two possibilities in this situation, one is the spectrometer's own problem, and the precision is not enough to produce abnormal data.

One is that there is a problem with aluminum alloys, generally speaking, aluminum alloys contain some other trace elements such as magnesium, titanium, zinc, chromium, silicon and so on. If the precision of the spectrometer is very high, the readings can be displayed even at very low levels.

Hello! Dear, there are generally two possibilities for this kind of finch luck, one is the problem of the spectrometer itself, and the precision is not enough to produce abnormal data. One is that there is a problem with aluminum alloy, generally speaking, aluminum alloy contains some other trace elements such as magnesium, titanium, zinc, chromium, silicon and so on.

If the precision of the spectrometer is very high, the readings can be displayed even at very low levels.

This is the data of the aluminum alloy typed out by the spectrum.

Whether the spectrometer is calibrated for the curve, or if there is a problem with the selection of its own program.

This is the curve correction and program selection of customer feedback they don't say.

Then you need to ask clearly, if the program is set up incorrectly, it will also be inaccurate.
