The Dynamic Reaction Monitoring Facility (or DReaM Facility) allows researchers to monitor homogeneous reactions in real-time, under their normal reaction conditions, with a variety of analytical techniques.

As well as kinetic data, the DReaM Facility can also help researchers shed light on reaction intermediates and by-products, allowing a comprehensive picture of all aspects of the reaction in solution to be constructed.

An EPSRC grant was awarded in July 2016 to fund the equipment purchase.

Until July 2018 significant method development and testing will be undertaken by internal users.

The reaction can be set up in the fume-hood (a Schlenk line and glove box are also available) and the reaction mixture is pumped through flow cells in the NMR spectrometer and the UV spectrometer.

Samples can be taken from the flow pathway and directed to HPLC and/or mass spectrometry analysis. Volatile samples can also be taken from the reaction headspace to a second mass spectrometer.


  • Bruker 500 MHz NMR spectrometer with a nitrogen cooled Prodigy cryoprobe. Bruker’s InsightMR flow tube is used to flow the reaction mixture into the NMR spectrometer.
  • Bruker MicrotofQ Mass Spectrometer
  • Agilent 1260 series HPLC
  • OceanOptics UV Spectrometer
  • Hiden Mass Spectrometer for analysis of the headspace volatiles

NMR Spectrometer

nmr-spectrometer-dreamTaking centre stage is the DReaM Facility’s Bruker 500 MHz NMR spectrometer with a nitrogen cooled Prodigy cryoprobe. Bruker’s InsightMR flow tube is used to flow the reaction mixture into the NMR spectrometer, where NMR active species can be detected and quantified. The Prodigy cryoprobe can be used at temperatures from -40 °C to 80 °C and NMR active nuclei from 15N to 31P, also well as 1H, 2H and 19F, can be observed.

Mass Spectrometer

The Facility houses a Bruker MicrOTOF-Q Mass Spectrometer which uses electrospray ionisation time-of-flight (ESI-TOF) as an ionisation technique. This system can be used to obtain accurate mass data for molecules in solution – particularly useful to obtain complementary information for compounds where no (or few) NMR active elements are present.


hplc-dreamThe Facility hosts an Agilent 1260 Infinity II series HPLC with three detection methods:

  • Refractive index (RI) detector
  • Ultra-violet (UV) detector
  • Evaporative light scattering detector (ELSD)

Where samples are compatible with the HPLC columns, samples can be injected from the flow loop into the HPLC. The system also has a manual injector for samples which require work-up in advance of HPLC analysis. Using a chiral HPLC column allows us to investigate enantiomers present in the reaction mixture that can’t be distinguished by NMR.

UV Spectrometer

The flow cell for the OceanOptics UV spectrometer is positioned after the NMR spectrometer in the flow loop but before the reaction mixture returns to the reaction vessel.

Headspace Mass Spectrometer

headspace-mass-spectrometer-dreamWe have a Hiden HPR20 Mass Spectrometer for analysis of the headspace volatiles, using electron ionisation (EI). If your reaction is emitting gaseous by-products in the range of 1-300 AMU, these can be detected.

Fume hood and glovebox

We have a fume hood with Schlenk line for setting up reactions under inert conditions. If reactions are extremely air-sensitive, there is also an MBRAUN glovebox that can be used as an alternative.
