Brief
Aarhus Universitet har inngått en avtale med BRUKER NORDIC DENMARK, FILIAL AF BRUKER NORDIC AB om å levere et toppmoderne 500 MHz NMR-spektrometer for flytende tilstand til Østjylland, til en verdi av 4 000 000 DKK. Spektrometeret skal brukes i organisk kjemi for karakterisering av syntetiserte organiske forbindelser og koordinasjonskomplekser, samt analyse av organiske materialer innen miljøvitenskap, matvitenskap og biokjemi. Det skal støtte høykapasitetsdrift på tvers av flere forskningsgrupper og muliggjøre variabel-temperaturanalyse fra minst -100 °C til +150 °C, med mulighet for utvidelse mot -150 °C uten probeskifte. Systemet må ha et BB-innstillingsområde som dekker 19F, 31P-109Ag og automatisk overvåke og justere puls-kalibreringer, shims, variabel-temperaturinnstillinger og qNMR-konsistenskontroller. Det var én tilbyder i konkurransen.

From the notice
One state-of-the art liquid state 500 MHz NMR spectrometer for use in organic chemistry, including characterization of synthesized organic compounds, synthesized coordination complexes, analysis of organic materials in environmental science, food science, and biochemistry. The spectrometer shall support high‑throughput operation across multiple research groups and provide possibility for variable‑temperature analysis over at least −100 °C to +150 °C with the ability to extend toward −150 °C without probe exchange or loss of routine automation to enable studies of highly reactive intermediates, such as radicals. The spectrometer shall have a BB tuning range covering 19F, 31P-109Ag (possibly with a small gap around the 2H lock signal). To sustain throughput and data quality, the system must enable automation that monitors and, when required, adjusts ¹H/¹³C pulse calibrations, three‑dimensional shims, variable‑temperature flow and heater settings, and qNMR consistency checks. In routine use, the instrument must be able to automatically select, parameterize, and execute the most appropriate small‑molecule NMR experiments to consistent specifications. Automation is particularly important for technical aspects of the measurement setup, such as shimming, 2H locking with deuterated solvents, variable temperature control, and sample exchange. These settings must also be accessible to advanced users who may wish for specific settings, such as shimming. As a workhorse the instrument must automatically change samples and output datafiles for analysis in external software, such as MestreNova. Automatic peak integration and plotting must also be possible directly in the instrument software package.
