Philips X'Pert 1 X-ray Diffractometer



The Philips X’Pert 1 X-ray diffractometer is a versatile device to characterise crystalline materials. It is capable of performing various types of measurements and analyses. The diffractometer has a stationary, centrally placed, X-ray tube with (para focusing) line focus and (parallel beam) point focus employing two goniometers for each type of focus. The line focus is mainly used for general diffraction work and phase analysis. Furthermore, it is used for determination of stresses in (sub) surface layers and line profile analysis. The point focus is mainly used for texture measurements. All measurements are done at room temperature. An oven is available to perform measurements at elevated temperatures under gas protection if required.
