Small Angle Scattering & Diffraction
B21 is a dedicated solution state Small Angle X-ray Scattering (SAXS) beam line that can accommodate a wide variety of aqueous-based and some limited organic solvent-based samples. B21 utilises a bending magnet source and delivers ~3 x 10^12 photons/sec directly to the sample.
The photons are distributed over a large 0.8 x 2 mm cross-section which is particularly helpful in minimising radiation damage while enhancing the signal of the particles. Our detector is currently configured to measure a scattering vector (q) range from 0.0032 to 0.38 Å-1.
SAXS time is offered through an application process via our users office.
Our end-station can be configured for full-automation from a 96-well plate, using the BIOSAXS robot (designed by the EMBL in Grenoble). However, we do offer Size-Exclusion Chromatography (SEC) coupled SAXS with either Superdex or Shodex SEC columns controlled by an Agilent HPLC. SAXS samples are measured through a temperature controlled capillary.
Samples should be shipped with the following information. A sheet of paper with a sample list (see shipping form above) and please include the following:
Name of Local Contact
Diamond Visit ID
Date of Visit
Name of Experimenter
Name of Home Institution
We highly recommend for samples on wet-ice that all samples be placed in a zip-lock bag. For samples on dry ice, the bag should be wrapped in paper-towels and taped.
