XPS

See more about elemental analysis on the side Element analysis


A rough overview of XPS-ThermoScientific characteristics

Purpose Chemical analysis
  • Probing elemental composition
  • Chemical state identification
  • Non destructive technique
  • Surface sensitive
  • Depth profiling possible by ion beam etch of sample
Performance Spot size Can be set between 30µm - 400µm
Probing depth Depending on probed element. Max probe depth lies within 10-200 Å.
Resolution Dependent on probed elements. Concentrations down to about 0,5 atomic % can in some cases be detected.
Charge compensation

Flood gun can be used for charge compensation of non conductive samples

.

µm

Depth profiling Purpose With ion beam etch the top layer of the material can be removed, to do a depth profiling
Ion beam size About 0,5x1 mm
Substrates Substrate size

Max 60x60 mm

Substrate thickness

Max height about 20 mm
