Welcome to the Chemical Characterisation and Analysis Facility (CCAF) wiki space

The Faculty of Science has recently combined the core technologies for Chemical Characterisation under the single organisational structure of the Chemical Characterisation and Analysis Facility (CCAF). These services are available to all researchers at the University of Bath, as well as researchers from other Universities and external companies.

 

The characterisation tools available include:

Mass Spectrometry

Accurate mass and isotope determination

  • ESI and APCI ionisation available, coupled to a time-of-flight (TOF) analyser. LC-MS service also offered.
  • Analysis of air-sensitive compounds using a glovebox - mass spectrometer combination
  • Analysis of intact and digested protein samples by nanoLC-MS

 

NMR Spectroscopy

  • Determination of structure in solution. Spectrometers ranging from 250-600 MHz are available, and a complete range of modern multinuclear experiments can be run.

NMR Spectroscopy in Pharmacy and Pharmacology

NMR Spectroscopy in Chemistry

 

X-Ray Diffraction

              X-Ray Powder Diffraction (XRPD) - fingerprinting of crystalline powders or crystalline deposits on matrix. Determination whether a sample is crystalline or amorphous.

              Single Crystal X-Ray Diffraction - Full structural characterisation from a crystalline sample of material (i.e. shape of molecule, content of molecule, all geometric data, how molecules pack together, intermolecular forces).

 

Other Techniques

Elemental Analysis (CHN) -  Analysis of a material to determine mass fractions of carbon, hydrogen and nitrogen within the sample.

Differential Scanning Calorimetry (DSC) -  Technique used to determine endothermic or exothermic physical transformations. Widely used to ascertain sample purity and to study polymer curing.

 

For further information on availability and costs, please do not hesitate to contact the service managers direct via the individual service pages linked above, or the Head of CCAF (Dr Anneke Lubben) by email or phone 01225 386172 (x6172).
