Hi all
I was hoping someone could help me identify a REE oxide mount I found tucked away that I have somehow missed over the years. It is labelled "P&H REE2O" and has six glasses mounted on it. As far as I can determine from EDS, their element content is as follows:
1) Pure Si-Al-Ca glass - no REE
2) Si-Al-Ca glass +Nd-Tb-Lu
3) Si-Al-Ca glass +La-Sm-Ho-Yb
4) Si-Al-Ca glass +Ce-Eu-Ho-Tm
5) Si-Al-Ca glass +Pr-Dy-Er
6) Another Pure Si-Al-Ca glass - no REE? Not sure why there would be two blanks on this mount though, perhaps just low level and not detectable by EDS?
I have the other P&H single element Ca-Si-Al REE standards, but nowhere can I find any information on these multi-element P&H REE xtals. Is anyone able to shed any light on these, were they distributed or custom made, is there any certified numbers for them?
Cheers
Hi Ben, they're definitely glasses not crystals, see here: http://www.pandhdevelopments.com/reeg6.html
There are 4 with 3-4 REE each in supposedly interference free combinations at around 4wt% each, one is a blank, and one has all REEs at around 0.5wt% each.
We had this mount in Clausthal in Germany where I did my PhD. I could ask them to send copies of the P&H analysis certificates. Or have a look through my old files if I've got a copy myself.
Cheers, Karsten
Holy crap Karsten, I must be losing it. I swear I searched the P&H website and could only find those single element glasses. I think I need to go the way of Old Yeller.
That would be awesome if you could find the data for it. I probably wont use it often but would be good to enter into the database. Thanks again.
Cheers
Hi Ben
I use those stds, I have the analyses (by AA I think) - I can send them to you.
All the best
