Hi Taray, the ones we get, very old tech and cheap have full Zn can, covered with thin plastic wrapper. This one is a C size cell, enough to supply materialt to everyone on the group- A shame to waste

Arrowhead using a modified beam, 1mm diameter, and a tungsten shield on the Si-PIN (~1mm entrance hole): Displayed here in LINEAR mode to show the relative abundance of the detected elements. Geo

Geo I have attempted it before Some of these batteries have only a Zn paste lining which is difficult to separate out No actual metal case like the old days Dismantling the steel external casing is

Save a dead Zinc-Carbon dry cell from the trash can. Take it apart, save the manganese based electrolytic in a min plastic baggie. Only a gram or 2 is needed, but also save the ZInc metal can and

Good results with ordinary small pebbles and sand from ant hills, collected in 2011 by J.H. These were originally comingled with some tramp Trinitite shards, which has been removed. From earlier

Thank you *so much*, Dud!! I've been waiting 50 years for an analysis. As everyone knows, wet chemical analysis of REEs is difficult - I tried, but the high density liquids are above the reach of my

Nice Dud.Having an official assay like that is invaluable. Especially if you can circulate the samples for us to test and compare our outfits to the commercial analysis.Geo

Dave, Attached are the XRF shots of the two Mt Pass Bastnasite samples you sent me The large sample (#1) that had the galena stringer in it was shot on both sides as well as the "sparkly" stringer

Thanks Taray, and I assume they cut off the needle after tying the knot? George To: [email protected] Sent: Thursday, December 17, 2020 8:43:16 AM Subject: Re: [XRF] Ethicon sternal suture [Edited Message

I’ll take a guess and say that bulb powder was Zn Oxide for its high reflectance and diffusion for that nice even look. Dud Sent: Saturday, January 9, 2021 5:02 PM To: [email protected] Subject: Re:

Thanks Dud, and I did include liquid dish soap after you reminded me about a surfactant while back, thanks for that too. Back when we had "frosted" incandescent light bulbs, a few burned out ones were

I though the Sr was your sample holder. Feldspar will break down and weather by hydrolysis forming kaolinite which is a hydrated aluminum silicate commonly called kaolin clay. It’s usually white,

This outfit can go as high as 52.9kVp, but there just are not enough atoms of Eu to detect in any of it using my XRF. Same goes for Cs, U Th but their radioactive decay can easily be seen. It can see

Geo, Unfortunately Eu is one of the rarer REE's with a crustal abundance from 0.8 to 2 ppm. It does a Ca replacement in plagioclase feldspar which, based on the granitic texture of your anthill sands,

Source of Europium near Trinity Site? We know from literature that Eu-152 is not a particularly abundant fission product. Now we knpw there is Eu-152 in sand that was not melted or subjected to the

It looks great, and can be adjusted for best results. Thanks for showing. Geo To: [email protected] Sent: Thursday, January 7, 2021 7:21:07 PM Subject: Re: [XRF] arsenic sulphide Here is close up pic of
