Yeah. I can’t run Nd dynamic because there’s a couple of dalys where I’d need faradays 🥲

Maybe I should start running hafnium so I feel better about my post-TIMS world 😂

Graph of neodymium isotope values from my new MC-ICPMS. Pretty scattered values compared to very stable TIMS analyses.

Fucking hell… this doesn’t bode well for international collaboration does it?

First tantalising glimpse of the plasma earlier this week. Hopefully we’ll get an ion beam next week, but very pleased with the progress so far. So excited for the cool research we can do with this.

That’s the idea! They just got a new triton and they wanted a hand setting up small sample size Nd! It’s been fun playing with the triton!

Any chance of some more details? The sticker is that I need them delivered flat-packed and then built/installed on site 🫠

Ok UK isotope folks: do you have a clean lab? Do you have polypropylene laminar flow exhausting fume cupboards?
Where did you get them??

No I haven’t but that sounds super interesting! We used to run the cuts on the TIMS (💀) but we have an ICPMS now thank god.

Column calibrations amirite? 🙄

Running one column today because I love pain apparently.

A single column in a clear rack. The lab space is white and there are reagent bottles around.

After no papers published last year (😅) it’s my second day back to work today and I have 2 drafts in my inbox already! Sometimes hard work takes a while to come to fruition, I guess!

"Your future is a horror story written by your crimes," is such an absolute A+ literary line that you'd be forgiven for forgetting it comes from the Muppets.

Got ID’d buying a bottle of wine just now and when the guy behind the counter saw it he said “1991?! Oh wow, I’m sorry”
Nah mate, you’re good! 😂
