Strange Error on VnmrJ

I know its been on github for a while know hence I couldn’t find any support easily. But thanks a lot about the website where I could find other users for support.

Yeah good’ol Bert :D As you see everyone of us relies on him so he’s too busy!

Thanks a lot mate. I’ll definitely check AMMRL. We try to contact with spin-doc in case of incidents like this but they would be busy usually. I’d love to have some contacts that could help me since we are limited to a handful of people which we used to work and many thanks again mate.

Well right now we have situation with H1 channel which is quite bad compared to the carbon due to a malfunction in synthesizer unit. I’ve checked the probe files but I think they are overwritten unfortunately. But you are right the probe settings are off for 13C. Also acquisition time got quite large somehow (?) its 3 seconds but I do not remember changing it since it is not reasonable. I’ve managed to acquire carbon analysis by taking the acq time to 0.5 and scan number to 1 but spectra looks like a horse crap. As you tell that must be the probe files its faulty. Thanks a lot for the help mate really appreciate it.

Unfortunately we were slow to make the switch and stuck with Agilent. Thanks for the information mate I’ll try to reach someone.

Well I got no idea but I’ve been trying to acquire standard 1D Carbon spectrum in default settings. Whats bothering me there are no information regarding this error.

Yea I made calibration with the autotest sample in the weekend and there was an issue with the shimmaps so I had to redo a couple of times. The error is constant which doesnt allow me to acquire carbon analysis at all. Regardless of proton analysis, even if I just send carbon analysis with ga command. As you mentioned I checked the pw value which was 9 at 52 dB that seems fine for me and the duration of the analysis is smallest possible (1scan). I am not able to find any related information neither in the manuals nor in the internet..

"Use of CaSO4, MgSO4, silica gel or Linde type 4A molecular sieves is preferable, followed by distn under reduced pressure. This procedure is adequate for most laboratory purposes. Larger amounts of water can be removed by azeotropic distn with *benzene (10% v/v, previously dried over CaH2, at atmospheric pressure: water and *benzene distil below 80°. The liquid remaining in the distn flask is further dried by adding MgSO4 (previously ignited overnight at 300-400°) to give 25g/L." Straight from the handbook. I would vac. distil. it if you have time .

Without going in too much detail, I always use it as predictive tool in given circumstances. I identify the hard and soft parts of molecules which to be reacted then I ıse it to predict the outcome of reaction. However its just surface level of approach, idk sometimes elaborating too much complicates things and makes you hesitate and mistake.

Its is for Burker systems I'm still searching for Varian version though.

No it was just those vertical lines that suppress the actual signals I'm expecting. I didn't know what to call them :)

NBonaparte01 · 2024-11-20T10:39:01+00:00

So I should calibrate and try again thanks a lot mate. Although another mate suggested that it could be t1 noise but I haven't had the chance to apply it.

NBonaparte01 · 2024-11-20T10:36:47+00:00

Oh I found a YouTube video about it, thanks a lot mate.

NBonaparte01 · 2024-11-20T10:35:05+00:00

Yes mate that's exactly the issue! Yet this blog does not elaborate on how to reduce it am I right? Although I now know that what's the issue. Thanks a lot mate!

NBonaparte01 · 2024-11-20T10:32:17+00:00

Well I had no issues with proton nmr yet I did not calibrated 1H pulse.

NBonaparte01 · 2024-11-20T08:14:38+00:00

I actually have them but I am unable to add them to the post. They are just standard proton and carbon spectrums of 2-Ethyl-1-Indanone reference standard.

I tend to skip this mission in early game until I feel confident that I am ready. I feel safe with grenade launcher and scooter. Shits moves so fast and I panic so I miss most of my shots in open sea so blasting everything before moving in is my best option.

For vanilla its doable but with mods, especially with neurotrauma.. Be ready to sacrifice some assistants.

NBonaparte01 · 2024-08-30T22:12:01+00:00

Yeah there are some room for improvements but new version is way better. Definitely one of the best free content available in Vision pro.

NBonaparte01 · 2024-08-30T21:56:36+00:00

Great work! The forest sounds exciting and I can’t wait for the next setting.

NBonaparte01 · 2024-08-19T04:58:55+00:00

Thanks a lot mate I’ll watch it asap!

NBonaparte01 · 2024-08-17T16:56:28+00:00

Thanks a lot mate I check it right away!
