SAXS spectrometer for high temperature studies of fluids

A new construction of a high temperature set-up for small angle X-ray scatt ering (SAXS) measurements on corrosive and volatile fluid systems is presen ted. The sample cell from single crystal sapphire is sealed with a special metal wire technique. The cell with the surrounding high temperature furnac e is integrated in a homemade SAXS-spectrometer This technique has been emp loyed up to 1000 degrees C for the example of SAXS-measurements on fluid Kx KCl1-x solutions which are briefly discussed.
