Equipment

The Clever Lab is equipped with a range of techniques for multistep organic and inorganic synthesis, compound purification, structure elucidation and analysis of multiple properties. Besides the below listed machines, the Department of Chemistry and Chemical Biology at TU Dortmund University, as well as its embedding in the University Alliance Ruhr, opens possibilities to access an even wider range of spectroscopies, microscopies and other methods such as EPR, time-resolved fs spectroscopy, TEM, AFM and many more in collaboration.


NMR spectrometer

500 MHz Bruker Avance neo NMR spectrometer with different probe heads, temperature control unit and sample changer. A range of further NMR spectrometers up to 700 MHz is available in the department.


Mass spectrometer

High-resolution Ion Mobility-ESI mass spectrometer Bruker timsTOF © Ralf Maserski​/​TU Dortmund

High-resolution Ion Mobility-ESI mass spectrometer Bruker timsTOF with HPLC and syringe pump infusion, glove box connection and cold spray ionization (cryo ESI) source.

This machine is not only suited to obtain the mass/charge ratio of supramolecular analytes with high precision and isotopic pattern resolution, it also delivers a value for the gas phase ion mobility, which can be converted into a collisional cross section (CCS in Å2). CCS values are indicative of an ions size and shape and can be used to distinguish isomers (with same m/z), simplify the analysis of complex mixtures and obtain valuable information about conformational flexibility and structural switching processes. We further use software tools to calculate theoretical CCS values from molecular models or X-ray structures in order to compare them with the experimental values.

The cryo-ESI source allows injection of analytes at much lower temperatures than usually applied in ESI sources, thus enabling the MS detection of very fragile coordination compounds or non-covalent adducts.


Diffractometer

Single crystal X-ray diffractometer Bruker D8 Venture © Ralf Maserski​/​TU Dortmund

Single crystal X-ray diffractometer (Bruker D8 Venture, with Incoatec Microsources 3.0 Cu and Mo, Photon II detector) for crystal structure elucidations of organic, inorganic, supramolecular and biopolymeric species.

In cases where microscopic crystal sizes, enormous units cells, highly disordered side chains and solvents lead to poor diffraction, we are fully equipped to freeze mounted crystals, kept in standardized pucks, contained in transportable dewars, down to liquid nitrogen temperature and bring them to synchrotron sources such as DESY’s Petra III, P11, beamline in Hamburg to collect diffraction data.
