Secondary Neutral Mass Spectrometer (SNMS)
Ppm-resolution elemental surface and bulk analyses of vacuum-stable materials. Depth profiling of surface layers to 100 µm (with up to 1nm depth resolution).

Appropriate candidates for SNMS elemental analysis or depth profiling include:

• Ceramics: bodies and glazes
• Glasses
• Rocks and minerals
• Fossil material and (de-proteined) bone
• Metals: non ferrous and ferrous (eg trace elements in steels)
• Semiconductors
• Multiple component materials (such as a conductor with a non-conductive coating)
• Polymers (surcharges apply)

Example data:
Depth profile of an Al-SiO₂-Si multilayer.
