Steve D's lump vs Geo's blob.XRF purity? Fe investigation.
30kVp-25uA. Si-PIN. run times similar, time adjusted as needed so Fe peaks are same height.
Difference in hump is aluminum filter .adjusted to get larger beam for Steve's larger sample. His is also much? thicker.
White ghost is my Blob.Blue is Fe peak selected by Peak Search program.
Steve's scan shows some different peaks than mine.
.mca attached for the lump.
