A simple device was developed for a moisture-proof X-ray diffraction analysis. The device consists of a simple plastic ring where one side was glued on with a thin film to let in the X-ray beam and the other side 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 very effective film to minimize the moisture intake, and an optimum ring height to maximize the X-ray intensity. Finally, this simple device was successfully verified that it can protect the anhydrous CaCl2 (hydrophilite) up to 4 days in ambient air.
