Dear AMMRLers,
We are looking into adding to our fleet of instruments a Bruker system that can do both liquids and solids experiments and I am thinking about whether we should get a standard or wide bore magnet. The wide bore solids probes have better capabilities/configurations than their narrow bore equivalents which makes them more appealing to get. Since we plan on having liquids capabilities as well, and I am not aware of any WB liquids probes, I am curious about the performance of standard liquids probes in wide bore magnets. I know that using special collars with the narrow bore probes will help center and position the coil, but I am wondering if anyone has had issues related to shimming, resolution, sensitivity etc. or any other things that should be of concern. Also, is there a significant difference with cryogen boil off and hold time of WB magnets compared to standard bore magnets. I would greatly appreciate it if anyone can share their knowledge and experiences with such a setup.
Regards,
Joel
