Ultra Pure TiO2?

[Probeman]

Does anyone have a very pure TiO2 crystal or glass with ICP-MS or other trace characterization?

We want to test it as a suitable "blank" standard for rutile/anatase trace element analyses.

I suspect these might be quite pure:

Edit by John: Thanks! We will check them out.

We bought some synthetic rutile from P&H developments in the UK recently which is 99.999%, single phase. We have mounted it and, although we've not tested it thoroughly yet, it is looking good so far.

So messrs Plant and Hopkins are still producing standards. That is good to know. I thought they had retired......

Tim Hopkins pops in here to use our SEM occasionally. I think he is now on his second retirement. He seems to spend most of his time in the Alps and just makes up a few standard blocks now and again to help fund his playboy lifestyle. He's got the right idea!

Hi John

Not sure these are pure enough, but they're well characterised.

A casual search of the Internet does not show them, do you have contact info or a web site?

Yes....He's been at that for a number of years now. Always used to brag about living from the wife's old people's home in Glossop or somewhere like that out there. I see it's been all change at Manchester, but I have asked one of my old colleagues if they know of Dave Plant's whereabouts. See what happens......
I could use doing a bit of standard updating here too......
