Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. In crystals of macromolecules, it is the degree of order in the crystal ('quality of the crystal') that limits the resolution of X-ray crystallography.
The 1st order diffracted light is recorded 2.476 cm from the optical axis. The transmitted diffracted light is collected at a screen 10 cm away from the crystal and perpendicular to the optical axis. A typical price for an average quality sample would be around £560 but all samples have individual tailored quotes prepared based on a visual inspection of the crystals and any specific experimental requirements. A monochromatic light is incident with an angle of 10o on a diffraction grating crystal that has a grating period of 15 um. Prices start at £395 per sample for routine cases.

These are based on the nature of the sample and the information required they include:Ī) full structure determination of routine samples (0.5 mm - 0.1mm crystal size)ī) full structure determination of very small crystals (down to a few microns in favourable cases).Ĭ) absolute structure determination of chiral compounds*ĭ) variable temperature experiments, for example to study phase changes (80-500K)Į) non-air atmospheres, for example to study hydrogen storage. Single-crystal X-ray Diffraction is a non-destructive analytical technique which provides detailed information about the internal lattice of crystalline. Fully re-equipped in 2011 our X-ray diffraction facilities are at the cutting edge of the technique.Īccess to state of the art facilities allows us to offer a comprehensive range of single crystal structure determination options providing the 3D structure of your material at atomic resolution.
