SYSTEMS

Sigray provides a full suite of synchrotron-like systems for everything from compositional analysis & chemical speciation to 3D microstructure. Each system features our patented x-ray component technology.

 

AttoMap MicroXRF

Micro x-ray fluorescence (microXRF) provides quantitative analysis of the elemental composition of samples and can provide thickness measurements of buried layers.

Key Features:

  • Highest resolution microXRF at <8 um
  • Down to single atomic layer sensitivity, with trace elemental sensitivity down to sub-ppm (femtogram)
  • Performance comparable to synchrotron microXRF

Applications:

  • Thin film measurements (e.g. semiconductor)
  • Contaminants
  • Trace-level elements in biological tissue or geological samples
 

for measuring elemental composition & distribution
