Dear users,

the 300 MHz instrument in inorganic chemistry remains out of service due to a broken probe (sensor unit). We are currently negotiating with the manufacturer and will inform you on Wednesday about an interim mode that covers partially the missing spectrometer capacities.

As of now, scientists from inorganic chemistry please use the AV300oc and AV499 for your routine experiments (please observe the sample concentration restrictions on both machines: https://nmr.chemie.uni-koeln.de/nmr-abteilung/auftrag/probenvorbereitung) for H and C experiments. For heteronuclei, there will be an alternative available hopefully from Wednesday.
