Bruker 300MHz NMR
Our 300 MHz NMR is the standard instrument for the routine measurements of the working groups of the Institute of Chemistry. It is operated with a 2-channel broadband sample head and is equipped with a 60-sample autosampler for high sample throughput.
- Magnet: Bruker Ultrashield 300 MHz NMR with 60 slot BACS autosampler
- Sample head: BBO 2 channel (proton, broadband) 5mm sample head with Z-gradient and ATMA (its design ensures increased sensitivity at the broadband channel and is therefore optimal for routine measurements).
- Console: Bruker Avance 3 Nanobay
- Software: Topspin 3.6.4
Bruker 500MHz NMR
The 500MHz NMR is available for somewhat more difficult tasks. With its tripleresonance sample head with ATMA, the nuclei H, C & N can also be measured in automation in the 24-slot autosampler. Due to the ideal connection of the chiller or an N2 evaporator and the additional cooling of the shim system, measurements can also be carried out well away from room temperature.
This spectrometer and the TXI measuring probe were financed by an infrastructure project of the Karl-Franzens University of Graz and the Future Fund Project FrontierNMR of the Province of Styria (Project No: PN1109)
In addition, a SEF probe for 19F measurements is available.
- Magnet: Bruker Ultrashield 500MHz with 24 slot Samplejet sample changer
- Sample head: 5mm tripleresonance (H, C, N) ATMA with Z gradient; SEF 19F sample head; tripleresonance (H, C, N) with Z gradient
- Console: Bruker Avance NEO
- Software: Topspin 4.2.1 (Attention: To interpret data from this instrument using MestreNOVA, a version >12 is required)
Bruker 700 MHz NMR
The most powerful NMR in our department is the Bruker 700MHz NMR with tripleresonance Cryoprobe with ATMA and Z-gradient. Due to the additional cooling of the sample head, the electronic noise can be reduced to a minimum, which further improves the sensitivity of the spectrometer.
- Magnet: Ascent 700MHz
- Sample head: Tripleresonance 5mm Cryoprobe with Atma & Z-Gradient
- Console: Bruker Avance III; Cryo platform
- Software: Topspin 3.7.0
IR (infrared) spectrometer
As an additional spectroscopy method, we also have a Bruker Alpha IR spectrometer, operated with an ATR attachment for simpler and sample-saving analysis.
For interested parties outside the Institute of Chemistry, it is possible to have measurements carried out for a fee. In principle, it is possible to use standard experiments as well as to develop more complex solutions.
