  • Open Access Instruments

    400 MHz

    Our 400 MHz Bruker Ascend magnet is controlled with Avance Nanobay (Avance III HD) console and equipped with high throughput - 60 position - SampeCasePlus autosampler. Currently, dual channel 5mm BBO probe with Z-gradient is installed in the system. It is tunable over a frequency range that enables observation of nuclei between 31P and 15N, as well as 19F. 1H{19F} decoupled measurements are also possible. The probe is equipped with BCU I temperature control unit that allows NMR measurements at temperatures other than RT.

     

     

    300 MHz

    Our 300 MHz Bruker Ultrashild magnet is controlled with Avance Nanobay (Avance III) console and equipped with high throughput - 60 position - SampeXpress autosampler. Currently, dual channel 5mm BBO probe with Z-gradient is installed in the system. It is tunable over a frequency range that enables observation of nuclei between 31P and 15N, as well as 19F. 1H{19F} decoupled measurements are also possible.

    In principle, the above instruments, with currently installed probes, are more sensitive for heteronuclear (13C, 31P, …) detected methods (APT, DEPT, etc.) but they will also provide decent spectra for 1H proton detected NMR methods such as 1d, DOSY, homonuclear 2d (COSY, NOESY, ROESY, TOCSY…) and all inverse detected methods (HSQC, HMBC, etc.).

    Right after the experiment, collected spectra can be downloaded by the authenticated users for further processing and archiving.

    To gain access and have a possibility to submit and measure samples on your own, please contact Dr. Krzysztof Piech.

     

  • High Field Instruments

    600 MHz

    High field 600MHz Bruker Ascend magnet controlled with Avance NEO console, equipped with Prodigy BBO and 1.3mm CP-MAS probe to be installed soon. Stay tuned.

     

     

    500 MHz

    Our 500 MHz Bruker magnet is controlled with Avance III HD console and equipped with - 24 position - SampeCase autosampler. Currently, 5mm BBO probe with Z-gradient is installed in the system. It is tunable over a frequency range that enables observation of nuclei between 31P and 15N, as well as 19F. 1H{19F} decoupled measurements are also possible. The probe can measure in wide temperature range, from -150°C up to 150°C.

     

    In principle, this is restricted access instrument available for the NMR Service only. On special request, qualified individuals, may gain the access to the 500MHz instrument. For details see the instructions.

  • Solid State Instruments

    At present we operate one (soon two) instrument:

     

    400MHz

    Our 400 MHz Bruker UltraShield magnet is controlled with Avance Neo console and equipped with dual channel BB probe. Spectra of samples filled in 4 mm diameter rotor can then be acquired in single/double resonance.

    If the compound of interest is insoluble or unstable in solution and when information about the solid-state structure is desired this is the system to go for. Samples can be spun from 1kHz up to 15kHz. Variety of different nuclei including ,1,2H,  6,7Li,  13C,  23Na,  27Al,  29Si,
      31P,   can be measured by our solid-state NMR.

    After prior training instrument access may be reserved via https://iris.science-it.ch/

     

    600 MHz

    High field 600MHz Bruker Ascend magnet controlled with Avance NEO console, equipped with 1.3mm CP-MAS probe to be installed soon. Stay tuned.

    Externals

    We encourage external users to measure their samples with our systems. Once trained, you can prepare, measure, and interpret your own samples yourself! If your time is too precious, we will do all that for you. Isn’t that great? Try us out! For details and pricing, please contact Krzysztof Piech
