Witryna13 kwi 2024 · In this study, the tendency of having different grain structures depending on the impurity levels in AZ91 alloys was investigated. Two types of AZ91 alloys were analyzed: commercial-purity AZ91 and high-purity AZ91. The average grain size of the commercial-purity AZ91 alloy and high-purity AZ91 is 320 µm and 90 … WitrynaPrepare sample with devices that do not introduce extractable impurities Run sufficient controls to verify run-to-run stability within a batch Remove sample components that interfere with separation, ionization ... polymers that, when fragmented, result in multiple peaks of varying m/z.
