Conference on Phase Analysis: Identification and Quantitative Determination. Hull, 5–7 April 1972

Determination of cristobalite phase content in ceramic cores using various X-ray quantitative phase analysis methods

The aim of this research is to investigate different X-ray based quantitative phase analysis methods for determination of cristobalite phase content in ceramic cores. For this purpose, four popular routes including peak absolute intensity method, relative intensity ratio method, direct or calibration method and internal standard (or Alexander-Klug) method have been chosen. Some control samples ...

Method of Quantitative Phase Analysis by XRD Without Reference Material

This new method which is worked out in Isfahan University of Technology, makes it possible to analyze the phases quantitatively in minerals and powdered materials by X Ray Diffraction and without any reference material. To identify n unknown phases, n different combinations of phases, from fine and coarse fractions, or etc., must be obtained. Amorphous phases should not exist. Intensity ratios ...

Identification and Quantitative Determination of 4-Hydroxyisoleucine in Trigonella foenum-graecum L. from Iran

  Background: The seeds of Trigonella foenum-graecum L. (Fenugreek) are used in Iranian traditional medicine as blood sugar lowering agent. According to last investigations, hypoglycemic property is related to the amino acids of the plant specially 4-hydroxyisoleucine.   Objective: In this research, identification and quantitative determination of 4-hydroxyisoleucine in Fenugreek seeds from Sha...
