TXI probe in Paris

Since most of the synthetic chemists are gallivanting around Denver for the ACS meeting, I decided to put the TXI probe in Paris. This probe gets much better sensitivity for 1H detected experiments (like the HSQC) at the expense of less sensitivity for 13C (or other heteronuclei) detected experiments. So Friday afternoon I swapped the probes. I've noticed that I always have a trickier time getting Paris shimmed back into spec than any other instrument. Fortunately, I took advantage of some computer aided shimming and was acquiring data by Saturday night. So far it looks good. I'll probably leave this probe in the instrument for a couple of weeks so that I can collect some spectra on a sample in 90% H2O/10% D2O for a client. Turns out I get better water suppression with the TXI probe than the BBO probe.

With the start of the semester, the ACS meeting and a holiday next Monday, this week seemed like a perfect time to play these games.
