Saxs waxs analyzer

SAXS-WAXS Analyzer

Purpose

The SAXS-WAXS Analyzer skill provides structural characterization of nanomaterials through small and wide angle X-ray scattering, enabling determination of size, shape, and spatial organization at the nanoscale.

Capabilities

• SAXS data reduction and analysis
• Form factor fitting
• Guinier and Kratky analysis
• Pair distance distribution function
• WAXS crystallinity assessment
• Self-assembly structure determination

Usage Guidelines

SAXS Analysis

1. Data Reduction

   • Subtract background
   • Apply transmission correction
   • Merge multiple detector regions

2. Form Factor Analysis

   • Fit to sphere, cylinder, or other models
   • Extract size distribution
   • Determine shape parameters

3. Structural Analysis

   • Calculate P(r) function
   • Determine Rg from Guinier
   • Assess folding from Kratky

Process Integration

• Statistical Particle Size Distribution Analysis
• Directed Self-Assembly Process Development
• Structure-Property Correlation Analysis
