extra group meeting stuff
Jessica Piness
Hey everyone,
Thanks so much for your feedback on my dissertation outline! I appreciate the ideas and I’m going to get to work on a few of them soon.
I had a couple other things I wanted to mention:
1. I’ve come up with a way to wrap samples for DMA so they don’t get gunk all over the clamps. Picture is attached. Obviously, try not to run under cured stuff, but if you’re having issues the Teflon seems to work great. Let me know if you need help, there’s some on the bench top near the log.
2. If you want to get trained on the new ATR, please come see me sooner rather than later!
3. We need to replace the KBr windows on the FT-IR sample chamber. They get easily fogged because they are hydroscopic and the hot cell really exacerbates that. Our service engineer suggested that we cure a sample we get good spectra from with the plastic sample chamber window open to help dissipate the heat and see the N2 leaking affects the spectra. I know we don’t really want N2 leaking, but the windows are $200 and we’ll have to keep replacing them otherwise. Thoughts? Anyone have something they can run to test this?
4. Also, did we ever find where the acetone bottles went?
