  • Porosity of Concrete Measurement - Low Field NMR
    In the construction industry, concrete is a widely used functional material. Solid concrete has a large number of pores. Those pore states are different and the different states will result differences in its properties. Accurate testing of concrete porosity is a prerequisite for in-depth study
  • Therapeutic Dose: Extending QbD to Stability Testing
    of QbD is being extended to control not only the ongoing process, but the raw materials. Practitioners suggest that we look as closely at excipients as we currently do at active pharmaceutical ingredients (APIs). As a result, more companies are staring to measure things such as compressabilty, porosity
  • Study on Wettability of Coal Pores-Part 1
    As we know the principle of NMR test pore distribution, the first step is to fully saturate the sample with water, and then measure the original porosity and pore size distribution of the sample according to the correspondence between the relaxation time of the water in the pore and the pore radius.
  • NMR Cryoporometry-low Field NMR
    NMR cryoporometry (NMR-C) is an emerging pore characterization technology that can cover the test range of nanopores, can achieve continuous measurement of the same sample, and can directly and efficiently obtain pore size distribution, porosity, and other information. The test process has little
  • A Spectroscopy Guide for PAT
    , crushability, surface area, porosity, morphology and particle size distribution of excipients and APIs. Standard physical testing, while accurate, is slow and labor-intensive. Means are needed to make rapid, multivariate measurements on solid materials. This suggests spectroscopy. This article will
  • Sterilizing Filters: Right Flow, Right Size Critical
    This quick, one-time registration gives you access to members-only site benefits. Another common mistake is using 47-mm discs for testing. Tests for flow rate using 47-mm discs are meaningless, since they can evaluate only the porosity and thickness of the membrane itself. Critical and beneficial
  • Ultrasonic Flaw Detection
    Of all the applications of industrial ultrasonic testing, flaw detection is the oldest and the most common. Since the 1940s, the laws of physics that govern the propagation of sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal
  • Analysis of Pore Permeability of Oil-Bearing Shale Assisted by NMR-Part 1
    and magnetic fields, and contains two characteristic time decay constants: longitudinal relaxation time T1 and lateral relaxation time T2. Although rock physical properties and fluid characteristics were originally obtained from T1, T2 tests are now used because T2 tests are faster. Over the past two

  • Pairing GD&T with Industrial CT Helps with Moldmakers Part to Print Projects
    parts are scanned in a free-state environment, allowing for both external and internal components to be validated quickly and accurately without destructive testing. Jesse Garant & Associates Metrology Center is a global leading provider of industrial CT scanning services, JG&A Metrology Center

  • Organic coatings
    The porosity testing equipment .type 102. was modi- fied for this application.
  • Non‐metallic inorganic coatings
    The porosity testing equipment .type 102. was modi- fied for this application.
  • Summary
    Although used for nearly 20 years, porosity testing techniques and equipment are still not full standardized with regard to the number of variables which can affect the final use.
  • Porosity Testing of Polyester Vascular Grafts
    In actual practice, there are considerable variations in the equipment used for porosity testing .
  • Biotechnology, Chemical and Materials Engineering II
    The type of equipment for testing apparent porosity and body density is APBD-001 made by Jingda from Luoyang and the testing is running by GB /T 2997.
  • Strength and Stiffness of Porous Materials
    In practice with scattered experimental data, with low reli- ability at high porosities , andlor different types of test equip- ment being used to produce stiffness and strength data, the “quality of regression” may be a delicate matter to decide.
