DEVELOPMENT OF A SIMPLE DEVICE FOR A MOISTURE-PROOF X-RAY-DIFFRACTIONANALYSIS

A simple device was developed for a moisture-proof X-ray diffraction a nalysis, The device consists of a simple plastic ring where one side w as glued on with a thin film to let in the X-ray beam and the other si de was covered with grease to seal onto a base plate. This device was later optimized by selecting a good adhesive to glue on the film, a ve ry effective film to minimize the moisture intake, and an optimum ring height to maximize the X-ray intensity. Finally, this simple device w as successfully verified that it can protect the anhydrous CaCl2 (hydr ophilite) up to 4 days in ambient air. (C) 1997 International Centre f or Diffraction Data.
