UW CHEMISTRY NMR

I am trying to satiate the possible curiosity of some of you who might be wondering what is the substance of  the ‘VT troubleshoot’ you have been observing on the calendar.  Observations show that, when we try data collection at extreme temperature limits such as +70 C,  the target temperature very slowly drifts down i.e. about 1 degree in an hour.   When we use the system in and around 298K, one may not be able to see any adverse effect of this phenomenon.  Nevertheless, this subtle behavior probably has an equally subtle cause(s) and that is what we try to identify and remedy in these troubleshoot sessions.

I wanted to emphasize by this post that the VT system is alive and well for your routine runs.  Please let either Adrienne or myself know if you need any further help.
