AV500 is replacing the DPX400
The AV500 has successfully been moved to new location. The DPX400 is no longer available. The NMR laboratory will therefore be one magnet short between May and October, 2015.
For the AV500; IconNMR will be up and running during the first week of June, but with limited numbers of solvents.
For the AV600; Manual IconNMR will be available on demand and maybe one or two days a week for a limited number of hours.
A new instrument will be installed in September/October
A new 500 MHz Wide Bore NMR instrument will be installed in September, 2015. Main applications are within material research, both on biological samples and other types of materials.

NMR-laboratoriet på Kjemisk institutt UiB
Kjernemagnetisk resonans (NMR) spektroskopi er basert på en egenskap til atomkjernene som man kaller for spinn. Denne egenskapen gjør at elektromagnetisk stråling i radiobølgeområdet med den rette frekvensen kan vekselvirke med atomkjernene. Resultatet er et spekter som viser det magnetiske fingeravtrykket til molekylet og som også gir informasjon om hvilke omgivelser molekylet befinner seg i. NMR laboratoriet er lokalisert på Kjemisk institutt, 3 etasje i Realfagbygget, og er utstyrt med to (vi får et til i oktober, 2015) NMR instrumenter fra Bruker Biospin. Kjemisk institutt har en egen forskningsgruppe knyttet til NMR-spektroskopi. Denne gruppen driver med NMR-relatert forskning anvendt innen proteinstrukturer, naturstoffer, petroleumskjemi, biologiske membraner, porøse systemer og MRI-kontrastmidler. Forskningsgruppen i NMR-spektroskopi er også ansvarlig for tillrettelegging av NMR eksperimenter for de andre forskningsgruppene ved instituttet.
What is NMR?
Nuclear magnetic resonance (NMR) spectroscopy is based on a property of the atomic nucleus called spin. Because of this property electromagnetic radiation in the radio wave area with the right frequency may interact with atomic nuclei. The result is a spectrum that shows the magnetic fingerprint of a molecule, and that can also give information about the physical and chemical environment of the molecule. In our lab we use NMR spectroscopy to solve problems related to organic synthesis , protein structures, petroleum chemistry, natural compounds, biological membranes, MRI contrast agents and various types of porous systems.
The NMR lab
The NMR lab is located at the Chemistry Department on the third floor in Realfagbygget, and it contains two (for the moment) vertical bore NMR instruments from Bruker Biospin.
Bruker Biospin DPX400
The DPX400 spectrometer is no longer in use. It was discharged on May 20th. It was replaced by the AV500 instrument (more below).
The DPX400 magnet now belongs to the magnet museum located in the southeast corner of the Chemistry Department, 3rd floor. Back: DPX400. Front: Old 200MHz magnet.
Bruker Biospin AV500
The AV500 instrument is located in room 3062 (replacing the DPX400). When it is fully up and running, it will mainly used for short routine 1H and 13C experiments where the main goal is identification and characterization of organic compounds. It is equipped with a Broadband Observe (BBO) probe. The instrument has a automatic sample changer where the users can put their sample in queue using the IconNMR software. Several other probes are available for this instrument:
- Magic Angle Spinning (MAS) probes
- Diffusion probe: diff30 from Bruker Biospin, z-gradient (1200 Gauss/cm). Exchangeable rf-coils (1H and 13C).
- Broadband Observe (BBO) probe: BBO (1H, BB) from Bruker Biospin.
- Selective fluorine (SEF) probe: Selective observation of 19F with decoupling of 1H (SEF 19F) from Bruker Biospin.
- Flat coil probe (custom made) for NMR studies of surfaces.
Between May and October 2015 (when the new 500 MHz instrument will be installed) only the AV500 and AV600 instruments will be operational. This means that the AV500 will also be used for solid state NMR experiments in this period.
The AV500 in its new location in room 3062. Now with sample changer.
Bruker Biospin AV600
The AV600 instrument is located in room 3002. The instrument is equipped with a cryo probe, and is mainly used for high resolution NMR studies of proteins and macromolecules in the liquid state.
- You can run experiments on the AV500 instrument using IconNMR and the automatic sample changer. Contact Olav-Audun Bjørkelund for information about how to get access.
- You can book time on the AV600 instrument by filling out the request forms located in room 3002, or by sending an email to Olav-Audun Bjørkelund. Booking is done on a weekly basis. The deadline for booking is Thursdays at 4 pm.
Important: In order to book time on the instruments you have to have the proper training in how to use of the instruments (certified user). Contact one of the people on the list above for more information about this.
