X-ray Diffraction–Solving Problems with Phase Analysis

X-ray diffraction (XRD) can quickly distinguish between crystalline phases of a variety of materials, including cross-sectioned and layered samples. Presented by: Joe Swider, Ph.D., Senior Research Scientist, McCrone Associates The difference between two phases of the same composition can mean the difference between useful or toxic.
