Some??people collect pure metals?

I notice??most??metals in a pure form tend to have a silvery??with different shades of grey appearance .

This??has something to do with electronic structure??related to absorption and reflection of visible light in pure metals

Color??is a subject??familiar to UV and visible light spectroscopy.

One possible way to tell them apart is??specific gravity which has been discussed before..

?Now back to xrf..

These are sample of??relatively pure??scandium,rhenium,dysprosium and samarium

To analyze peaks??results go to

One can??interpret any element of interest for xrf for free up to about 40 KV due to xray limitations.

Once there was a good free xrf software on AppStore which covers a very broad??xrf range

Now it has been replaced by another paid app??probably from the same seller.

Interestingly this XspecApp connects to Dp5

I have no plans of purchasing yet

Poor ratings so far..

My samples are???barely a few gms (except??samarium??10 gms)and shot through a PE container?

Acquisition is only 3secs

?Xray 60 Kv 0.1 mA

Some of the peaks may be worthy of a longer acquisition time.

The pics are from the seller website??for convenience.

Thanks
