We optimized sample preparation in the form of beads for the XRF measurement by determining the most appropriate sample/flux ratio for each type of refractory. Calibration and validation standards were prepared from mixtures of reference materials, owing to the scarcity of refractory reference materials...
Good knowledge of reaction kinetics and mechanism, analytical methods (GC, GC-MS, HPLC, HPLC-MS, and NMR,) and characterization techniques (XRD, SEM, TEM, AFM, XRF, XPS to resolve mechanism-catalyst relationships in conjunction with catalytic performance. Excellent ability to work in a team an...
X-ray Fluorescence (XRF)andX-ray Diffraction (XRD)are important, complementary technologies to characterize both the chemistry and structure of various types of materials. The ability to determine the elemental composition of a wide range of samples for both simple and a...
Our x-ray tube fabrication facility can also create custom designs for XRD, XRF, or imaging. Measurement Services Trust your x-ray diffraction measurement needs to our highly skilled and knowledgeable team. Our accredited laboratories have the highest quality standards and carefully follow all ...
The bulk compositions of the fly ashes as determined by XRF are shown in Table 2. The uncertainty specified is the maximum wt.% difference between analysed and known values for appropriate standards. Crystalline phase composition – quantitative phase analysis To check the efficacy of the data coll...
