NMR Service measurements at 500MHz:
You may provide samples for service measurement from Monday to Friday. We shall run routine spectra within 24 hours (not on the weekend) and transfer the data to the NMR data servers of your group.
We are able to run all routine 1D and 2D spectra during the service routine with "routine samples".
Requirements for routine spectroscopy:
- sample concentration for NMR service:
1H NMR spectra: higher than 0.01mol/l (5mg in 0.5ml with M = 500g/mol)
13C NMR spectra: higher than 0.05mol/l (25mg in 0.5ml with M = 500g/mol) - filling height: Between 4 and 5 cm. 4cm is required for automation, more is not necessary. More than 5cm is not allowed (no spectra will be acquired with NMR tubes filled higher than 5cm!!!)
- for all spectra except proton NMR the information about sample amount, molecular weight and symmetry is helpful, without this information we shall run spectra with standard parameters.
- samples should be solutions not suspensions
- sample tube length should be longer than 17 cm without cap (no spectra will be acquired with NMR tubes shorter than 17cm!!!)
- please ask the operators in your group for overnight and weekend runs.
- please ask the NMR group if you need special experiments (e.g. temperature experiments).
- please write as clear as possible! (usage of the computer is allowed)
- please use only small letters and numbers (we’ll only use small letters, even if your sample contains capital letters or roman numbers!)
- please use only “–“ as spacer!
