I ran some maps that required a total of 9 elements (out of the 10 possible on my 5 WDS machine) and hence two map acquisitions. So rather than having one spectrometer sitting idle, I ran a map for one of the minor elements twice (once in the first map acquisition, then again in the second, same spectrometer).
When I want to crunch the maps through CalcImage (with aggregate intensity function on), it correctly recognizes that the second map is essentially already loaded in. Is there a clever workaround for me or should I simply run any aggregate intensity maps on two different spectrometers in the future (which has its benefits anyway)?
Hi Anette,
I just realized that you simply *cannot* have two elements with the same element, x-ray and spectrometer in Probe for EPMA (or CalcImage). Why? Because then there is no real way to tell them apart from each other, so that is that!
But you are correct, you can have duplicate elements in PFE and CI by using different spectrometers for the same element/x-ray pairs. But as I said before, although one can specify and calculate duplicate elements just fine in Probe for EPMA and CalcImage, unlike Probe for EPMA, CalcImage will not automatically aggregate the unknown duplicate x-ray maps for you as yet. I am working on that this weekend.
The best thing for now is to acquire your standard intensities with the duplicate elements in Probe for EPMA, then set the Use Aggregate Intensities For Duplicate Quantitative Elements checkbox in the Analytical Analysis Option menu dialog. And then prior to loading the duplicate x-ray maps in CalcImage, simply "aggregate" the x-ray intensity grid files (.GRD) with duplicate elements using Surfer.
CalcImage *will* automatically aggregate the standard intensities and then apply them to the manually aggregated x-ray maps from Surfer for improved precision on the duplicate elements.
According to Aoife it is easy:
