Dear users,

the damage at the 300 MHz instrument in inorganic chemistry requires a several weeks...months repair of the probe at the manufacturer.

As a first measure of compensation for inorganic chemistry users, starting from next week, on three days (Tuesday, Wednesday and Thursday) samples for heteronuclear measurements may be submitted to the 500 MHz instrument (operator mode) until 1 pm and will then be processed on the same day.

We will also implement a temporary solution for 1H/13C use of the AV300ac at a later point. However, this depends on the offer from Bruker, which still has not arrived. We will keep you updated and adjust our service correspondingly. In the meantime, please make use of the instruments in organic chemistry as announced earlier.
