diffractometer การใช้

• The actual components inside Brokenhillite can be determined using a diffractometer.
• There are 2 approaches to chamber and diffractometer design that are in use.
• For examples of X-ray CTR diffractometer apparatus, see refs 15-17 in
• An instrument dedicated to performing such powder measurements is called a "'powder diffractometer " '.
• To achieve this motion, the sample and detector are mounted in an apparatus called a four-circle diffractometer.
• This approach avoids putting a large mechanical load on the diffractometer goniometer, making it easier to maintain fine angular resolution.
• A paleomagnetism lab, an isotopic geochemistry facility, and an X-ray diffractometer are among other public services hosted.
• As mentioned above, the Powder Diffraction File contains powder diffraction data and is designed to work with a diffractometer to identify unknown materials.
• In some setups, the sample chamber can be detached from the diffractometer without breaking vacuum, allowing for other users to have access.
• A ?60, 000 single crystal x-ray diffractometer which uses x-rays to provide the three-dimensional structure of chemical compounds.
• The repetitive technique of crystallographic data collection and the often high symmetry of crystalline materials cause the diffractometer to record many symmetry-equivalent reflections multiple times.
• In 1948, North American Philips corporation ( Norelco ) introduced the first commercial X-ray diffractometer product in cooperation with the US Naval Research Laboratories.
• In the first method, the sample is fixed relative to the vacuum chamber, which is kept as small and light as possible and mounted on the diffractometer.
• In 1958, the Engineering and Research Laboratory was enlarged to accommodate six laboratory sections that housed specialized instruments, such as a direct reading spectrometer and x-ray diffractometer.
• A typical diffractometer consists of a source of radiation, a monochromator to choose the wavelength, slits to adjust the shape of the beam, a sample and a detector.
• It contains more than 20 major instruments and devices including a High-Resolution Mass Spectrometer, Infrared Spectrometer, X-Ray Quadrupole Diffractometer, Laser Raman Spectrometer, FT-IR Spectrometer, and others.
• Dai's team built the first neutron crystal spectrometer, the first neutron diffractometer, the first zero-energy thermal reactor, the first neutron transmutation doping of monocrystalline silicon, first large-sized electromagnetic separator in China.
• When a single crystal is examined in an X-ray Diffractometer such that the diffraction intensity is measured cylindrically around the crystal, it is convenient to use cylindrical coordinates to define the reciprocal lattice vectors and their terminal points.
• General criteria for judging the practical usefulness of detectors for topography applications include spatial resolution, sensitivity, dynamic range ( " color depth ", in black-white mode ), readout speed, weight ( important for mounting on diffractometer arms ), and price.
• The Lander would have its own payload for the characterization of the " in situ " measurements ( e . g ., close-up camera, panoramic camera, electron microscope, X-ray diffractometer, volatile detector, microbalance, mass spectrometer ).
