Quantitative Powder XRD Phase Analysis Software for Windows

General Description

SIROQUANT is currently being used by many industrial, scientific and academic organisations around the world. It has a logical user friendly WINDOWS interface including extensive on-line help. It requires an IBM PC (minimum 386DX processor) running WINDOWS 3.1 or higher. The WINDOWS version has been available since 1993 and has been extensively debugged during this time. The system is equally useful for industrial and research applications due to its unique method of operation.

PROFILE FUNCTIONS

SIROQUANT supports Gaussian, Lorentzian, Pearson VII and Pseudo-Voigt profile functions.
The March preferred orientation parameter is also refineable.

REFINEABLE PROFILE PARAMETERS

• Phase Rietveld scales.
• Line asymmetry.
• Preferred orientation.
• Line-width parameters, U1, V1, W1 & U2, V2, W2.
  (Note: Two line-width functions are allowed for each phase)
• Instrument zero.
• Pearson M or Pseudo Voigt shape functions.
• Unit cell dimensions (a, b, c, alpha, beta, gamma).

Refinements can be performed in several stages with different combinations of varied parameters.
An automatic refinement procedure (Auto - prescale) is also available and produces good ball park estimates for most samples as well as a providing a basis for further refinements.
