Dear Colleagues,
Are there any recommendations for which probe is best to use for metabolomics work ? (as in we are hoping to purchase a new Bruker probe with the main intention of using it primarily for metabolomics work). At the moment the considerations are a 5-mm nitrogen-cooled triple resonance inverse probe (TCI-Prodigy), a 5-mm room temperature triple resonance inverse probe (TXI), and a 3-mm room temperature triple resonance inverse probe (TXI, normally we are using 2.5-mm tubes in a 5-mm tbi probe for our metabolomics work, so a 3-mm probe is fine for us). Bruker recommend for our 600 MHz system either the 5-mm BBI or the 5-mmTXI probe since we do not consider a helium-cooled cryoprobe which is out of our budget considerations. Bruker do not recommend the nitrogen-cooled 5-mm TCI-Prodigy for metabolomics work, any experience with this probe for metabolomics work or what the problems might be ? Also, if anyone has S/N data for the 5-mm TCI-Prodigy probe, that would be grand.
Finally, any idea what the nitrogen-cooled Prodigy cryoprobe should cost about relative either to an analogous helium-cooled cryoprobe (half ? one third ? one quarter ?) or to a room-temperature probe (double, triple, quadrupole ?).
Many thanks in advance and will post a summary in due course.
Regards,
Karel Klika
