Qualitative X-ray Analysis
It is a waste of time to proceed with quantitative microanalysis from your XEDS spectrum without first carrying out qualitative analysis. First we will show you how to choose the best operating conditions, for both the microscope and the XEDS system. Then we will explain the best way to obtain a spectrum for qualitative analysis. Qualitative analysis requires that every peak in your spectrum be identified unambiguously, and with statistical certainty, otherwise it should be ignored. So you have to acquire a spectrum with sufficient X-ray counts to allow you to draw the right conclusions with confidence. There are a couple of simple rules to follow which allow you to do this.
