The aim of the Cronenbourg NMR Platform is to provide the scientific community on the CNRS Cronenbourg Campus and in private laboratories with top-level NMR equipment, know-how and expertise for solution analysis, whether for routine use or advanced studies.

Attached to UMR 7042 CNRS-Unistra-UHA LIMA (Laboratory of Molecular Innovation and Applications), it serves the scientific community of 5 UMR/UPR, 21 research teams, totalling some 220 users. Teams work on a wide range of research topics, including organic chemistry, polymers, molecular materials, biological compounds and materials science.

The Platform manages five NMR spectrometers at three sites on the Campus (École Européenne de Chimie, Polymères et Matériaux (ECPM), Institut Charles Sadron (ICS), Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS)). Four of its facilities are permanently dedicated to routine measurements.

ECPM Site :

• Spectrometer "ECPM 400 bis" : Bruker Avance III HD - 400 MHz – Topspin 3.6
  Direct probe X-¹H-¹⁹F BBFO 5mm (with ³¹P < X < ¹⁰⁹Ag – ¹⁹F / ¹H) wvith gradients
  Temperature : 298 K
  Sample changer "SampleCase+" 60 positions
  Routine spectrometer. Self-service by reservation of daytime programming slots.

• Spectrometer "ECPM 400 R" : Bruker Avance III HD - 400 MHz – Topspin 3.6
  Probe X-¹H-¹⁹F BBFO "Smartprobe" 5mm (with ³¹P < X < ¹⁰⁹Ag – ¹⁹F / ¹H) with gradients
  Temperature : de 213 K à 383 K
  Sample changer "SampleXpress Lite" 16 positions
  Research spectrometer. Dedicated to advanced experiments (quantitative, variable temperatures, titration, reaction monitoring, UV irradiation, relaxation, diffusion, etc.) and practical work at ECPM.
  Accessible by reservation only.
  Advanced experiments operated by Platform staff only.

ICS Site :

• Spectrometer "ICS 400" : Bruker Avance III HD - 400 MHz – Topspin 3.6
  Probe 5mm X-¹H-¹⁹F BBFO (avec ³¹P < X < ¹⁰⁹Ag – ¹⁹F / ¹H) with gradients
  Temperature : 298 K
  Sample changer "SampleXpress" 60 positions.
  Routine spectrometer. Self-service (ICS) with reserved daytime slots

IPCMS Site :

• Spectromètre "IPCMS 300" : Bruker Avance I - 300 MHz – Topspin 2.1
  Direct probe QNP 5mm (¹³C – ³¹P – ¹⁹F / ¹H) manually adjustable, non-automatic system
  Routine spectrometer. Self-service (IPCMS) on reservation of daytime slots

• Spectrometer "IPCMS-500" : Bruker Avance III HD - 500 MHz – Topspin 3.6
  Direct Cryoprobe X-¹H CPPBBO "Prodigy" 5mm (with ³¹P < X < ¹⁵N / ¹H) with gradients
  Temperature : 298 K
  Sample changer "SampleXpress" 60 positions
  Routine spectrometer. Experiments operated by Platform staff only.

The Platform has recently equipped itself with a wet lab for specific studies. In the interests of sustainable operation, the Platform also equips its various sites with a helium recovery system.

The Platform meets the requirements of our supervisory bodies, notably through auditable management.
