Other Specialized Sample Environments at P12<\/strong> allow Users to conduct custom experiments using advanced SAXS techniques or their own specialized setups. <\/p>\n\n\n\n

This mode is ideal for experiments requiring specific conditions or equipment not covered by the standard configurations. <\/strong><\/p>\n\n\n\n

Users are encouraged to collaborate with the beamline staff<\/strong> to plan and optimize their experiments. <\/p>\n\n\n\n

Similar to TR-SAXS, the beamtime<\/strong> for these sample environments are granted separately and require staff input for experimental planning.<\/strong><\/p>\n\n\n\n

\n Anomalous SAXS (ASAXS) <\/h3>\n <\/div>\n<\/article>\n\n\n\n\n

At the P12 beamline we offer Anomalous Small-Angle X-ray Scattering (ASAXS)<\/strong>, <\/p>\n\n\n\n

    \n
  • Energy range<\/strong>: ASAXS experiments can be performed across a wide range of X-ray energies 6-20 keV to exploit absorption edges of different elements, enabling contrast variation and selective probing of specific components.\n

      \n Temperature-Controlled In-Air Sample Stages: <\/h3>\n <\/div>\n<\/article>\n\n\n\n\n

      We offer temperature-controlled in-air sample stages,<\/strong> including capillary holders and specialized cells, for users needing precise control over sample temperature during SAXS measurements. This environment supports studies where thermal stability, melting, or phase transitions are critical.<\/p>\n\n\n\n

        \n
      • Temperature range<\/strong>: The stages support a broad temperature range, allowing measurements from 4\u00b0C up to 80\u00b0C<\/strong>, depending on the experiment’s requirements.<\/li>\n\n\n\n
      • Capillary holder and sample cell<\/strong>: Two temperature stages are available. A capillary holder for up to 16 capillaries (1.5 mm diameter), and a multi-cell setup (\u201csandwich\u201d cell) for gel, viscous solution, or powder. <\/li>\n<\/ul>\n\n\n\n

        \n Versatile in-vacuum Sample Exposure Unit: <\/h3>\n <\/div>\n<\/article>\n\n\n\n\n

        The in-vacuum <\/strong>is a highly adaptable sample exposure unit designed to accommodate a range of experimental setups, including microfluidics-based SAXS measurements. The sample exposure unit is equipped with an on-axis microscope, front and back illumination, piezo stage for precise sample alignment and\/or raster scan. Fiber port for sample illumination or in situ spectroscopy. and microfluidics feedthrough. This sample environment is typically used for in-vacuum microfluidics and scanning SAXS on bones.<\/p>\n\n\n\n

        \n User-Supplied Setups: <\/h3>\n <\/div>\n<\/article>\n\n\n\n\n

        Besides the in-house systems, we can support user-based experimental instrumentation. Please get in touch with the P12 team for assistance with integration and ensure compatibility with the beamline’s infrastructure<\/p>\n\n\n\n\n\n
