Quantitative Trace Element X-ray Mapping

[Probeman]

Here's an example of a set of quantitative x-ray maps we did earlier this year of a hydrothermal quartz sample, showing trace level variation (though no detectable Ti) and the pixel level detection limits:

Another example at the same conditions as above. First the quant weight percents:



And here the quant detection limits:

It is interesting to compare the above weight percent image in the first post, in which the color scale was adjusted manually, seen here again:



With this image below, which are the same data but just displayed using the automatic log scaling with no adjustment. The only downside I can see to the log scaling is that you have to calculate the actual weight percents from the log values in one's head!
