With a peak in the middle of the traditional SAXS region, a strong scattering pattern and a shelf-life of several years (when kept dry and in the dark) this powder is the de-facto standard for run-of-the-mill SAXS machines.

Unfortunately Silver Behenate is NOT the golden standard that one would hope for because:AgBeh

  • Silver Behenate varies from supplier to supplier
  • Silver Behenate degrades over time when subjected to air, humidity and/or light
  • Silver Behenate often shows peak splitting at higher orders, with peaks separated by about 1.7%.

Neverheless a Silver Behenate sample, when regularly refreshed works out as a nice, well accepted standard for many SAXS applications. Please see our technical note and literature references therein for further information on Silver Behenate.
