We will swap the inverse (HCN) probe into the 500
starting 9:00 am Monday, 05/12 and ending 5pm Friday (05/16) or 9:00 am Monday (05/19).
If you MUST run a 13C during this time, let us know!
We can make the broadband probe available for an overnight acquisition.
During this period you will be able to do:
* 1H on small amounts of material
* 2D experiments (COSY, TOCSY, HSQC, HMBC, etc.)
* 2H
You will NOT be able to do:
* VT (outside the -20 to +80 range)
* 19F
* 13C (you can actually do 13C, but the sensitivity will be worse than on
the standard probe)
* any other nuclei, except 2H
Regular sign-up rules would be suspended and interested users could request
any length of time they need.
Why are we doing this?
We are swapping the probe to address the needs of researchers who characterize
very small amounts of material. The inverse probe has twice the 1H sensitivity
of the standard broadband probe, and thus reduces experiment times four
fold.
If you are unsure whether the inverse probe could benefit your research,
please come and talk to us, we would be happy to discuss it with you.
If you think the probe swap is a great idea:
Let us know who you are how much time you need.
Remember, unless we hear from you, we will not change the probe!
If you think this is a terrible idea that will hinder your research:
Please let us know, and we will do everything we can to address your concerns.
