Small Angle X- Ray Scattering, model SAXSess mc², with sealed-tube X-ray generator, Anton Paar GmbH, USA

Features: SAXS system contains a X-ray sealed tube with both line and point focus arrangement with a resolution (i.e. scattering vector) varying from 0.03 nm-1 to 28 nm-1. The detectors available with the system are CCD (for only small angle) and Imaging plate (IP) detector which gives simultaneous mode for small and wide angle (up to 40o) data collection. SAXS system has an option of external vertical and tilt alignment with Peltier Heating/Cooling unit with a minimum temperature range from -30°C to 120°C. The system also works on reflection mode i.e. GISAXS with maximum reflection angle of 6°.

Performance: The SAXS system works with both line and point collimation mode. Acquisition can be done for both small as well as wide angle measurements. Various sample holders available are flow cell, paste cell, rotor cell and variostage with the options for tilting and rotational as well as transitional movements of the sample.
