After running the 19.2us peaking time and being satisfied with the tweaking and calibration, here are the results from a and overnight U L X-Ray test and for comparison an old similar test on the same very weakly radioactive sample using 4.8us PT (both in Gamma Spectrum Analyzer mode- not excited XRF)
The differences are subtle but real, with the clarity of large peaks and better separation on smaller peaks going to the slower peaking time.
However in gross analysis, both are very accurate and would probably be equally useful for element identification purposes.
Differences between the scans doesn't translate to a pretty picture, so only .mca's included here.
