Basic Principle
• Excite cell with stream of protons
• Cell is scattered
• Cell seeks to return to stable energy state by releasing energy and bring back scattered components
Basic Principle
• These emissions can be identified and traced back to specific elements
• This process does no damage to the subject atoms
Practical Applications
• Trace elements in art can be identified
• Individual metals can be identified within composite metal pieces
