$Glancing Angle X-ray Diffraction (GAXRD) Technique$

MDSC: Sample Preparation �Thin, Low Mass Samples �Minimize Thermal Gradients �Allow for Faster Periods, Larger Modulation Amplitudes �Thicker, Heavier Samples �Minimize Baseline Curvature �Improve Sensitivity MDSC: Sample Pans Standard Crimped �Low, Consistent Mass �Best Choice for MDSC Measurements �Solids, Powders, Films �Volatility may be an issue
MDSC: Sample Pans Standard Hermetic �Use for liquid/volatile samples �Higher Mass, Less Sensitivity �Use Heat Sink Compound MDSC: Purge Gas �Nitrogen �Economical �Wide Operating Range �Provides Good Sensitivity �Helium �Higher Thermal Conductivity �Facilitates Wider Range of Modulation Conditions
