Got my own NMR


So I had an amazing eBay acquisition and got an 80 MHz bench top nmr. I am so excited and I just wanted to share the first crap spectrum haha.

Thanks! I couldn’t believe it, but I got it and sent it in for repairs. Just got it back two days ago. I’m trying to decide what I want to run on it haha.

Oh by the way it’s a Thermo Picospin 80, so it’s an 80 MHz bentchtop NMR that only does 1D proton NMR experiments.

The Picospin is kinda neat since you don't need NMR tubes for it. Hope you have some fun!

Wow, that’s amazing! You must have gotten an amazing deal (or dropped a small fortune).

Side note: your spectrum would look less crappy if you integrated the CH as your 1 instead of the OH ;)

I am sure that I have no real appreciation of just how awesome this is.

Congratulations. This is seriously cool.

I got it for a crazy good price, practically a steal. I am running samples on it right now!

I have been on the lookout for one of these for several years now and I was so amazed I got one. I will include this in my next video for sure.

Awesome, I'm very jealous. I did a quick look, anyone with about $3500 USD to spare there is a pickospin 45 on eBay right now

That is an amazing deal. I have a similar situation at work, where we have several NMRs and almost no one working, so no lines, queues, or waits in most cases. But cost more than that just to keep full of cryogens.

Wow! This is THE tool a chemist needs and you've got it. Do you mind sharing how much you paid for it? You had it repaired by the manufacturer?

Do you have a youtube channel? Would love to see that baby in action.

If you want a nice compound, try piperine. It's fairly big but still easy to isolate from pepper. Of course I've never done actual purity checks of my samples, but by MP they are supposed to be clean after a few recrystallizations

Thanks everyone. I have spent a few thousand dollars getting this all together so it’s not super cheep. But it doesn’t cost nearly as much as a new one. If anyone is interested I started a YouTube channel not too long ago. I will be adding more to it in the coming weeks. The link to my first video is here. https://youtu.be/rdOZQio-KtE

Could that possibly be used to analyze some samples
of a few unknown wax compounds?

The samples are various fragments of hard waxy
substances used many years ago for sound recording.

The ingredients of these are fairly well known, but there is
some missing data.

Got my own NMR update


Just wanted to show a new spectrum of Ibuprofen with some DCM and Acetone contamination. I am getting better at running this thing, but man am I rusty at my interpretation. Please leave your feedback, I would love to know what everyone thinks.

i just love it. i would help you more if i could, i'm studying an NMR course at UNI (at home lol) right now, but i've been distracted by so many things lol, my prof would have the jaw on the floor knowing an amateur has an nmr at home even if it isn't a 300MHz

Very nice! (Can I ask the make/model of it? The NMR dealer I'm trying to get my college to buy one from is curious as to what winds up on eBay.)

The instrument is a Thermo Scientific Picospin 80. I think the resolution is pretty good considering it is the size of a microwave. However if I had my choice of a bench top NMR to have I would go with the Nanalysis unit since it also does 2D and carbon NMR. But hey beggars can’t be choosers.

So cool - how much did that set you back?

Is it straightforward to use, and what if any consumables does it use?

I spent about $2K to get the instrument and a bit more to get it repaired. The consumables are really just dehydrated solvents, if you wanted to use them, and an additional “cartridge” whit is essentially a big computer chip with a flow cell. Other than that I typically use scintillation vials to prep samples which is another consumable. It’s also a good idea to have some kind of drying agent for your samples if you are concerned about water getting in your sample. I prefer anhydrous magnesium sulfate for a lot of my prep work if I need to dry stuff.
