We have changed NMR charging rates. New rates are effective starting September 1, 2012. Continue reading →

The cantaminates has been successfully removed. The I400 is now up running with good performance on all four (1H, 13C, 19F, 31P) nuclei. Please protect our instruments. Handle your samples with intensive care. If a sample is broken or spilled into magnet, report … Continue reading →

I’m working on the probe cleanup. The I400 is not available for use probably until Thursday morning. Use the Gem300 for 19F and 31P during this period of time. Continue reading →

The probe on the I400 got contaminated by some user(s) lately. The contaminates give rise to two proton peaks around 0ppm. If you have broken a sample or had your sample spilled into the probe on the I400, you should … Continue reading →

Some users had problems with sample ejection on the VXR400 in the past few days. This was caused by sticky chemical deposits formed inside the sample delivery barrel and the probe. Please do your part to prevent this from happening. ALWAYS WIPE YOUR … Continue reading →

This Thursday, August 9th, 10am – noon. There are a few spots left – reserve by emailing Doug! Note: This session is now full. Continue reading →

I will be doing advanced NMR training the week of August 9th (next week)! These will be single 2 hour sessions focused on using the 2D and selective 1D NMR experiments in the IU VnmrJ menu. I will schedule sessions … Continue reading →

As a result of analyzing 2011-2012 NMR use, we will be increasing NMR rates $1/hour across the board except for the Gem300 which will have the same rate as the 400s. The increase is due to increased cryogen costs and … Continue reading →

The NMR webserver was down for a while this afternoon when ITG was doing network upgrade. It is back up now. Continue reading →
