Q:
When should destructive analysis
procedures be used?





A:
Destructive Analysis Procedures Should
Be Used When:



  • Large amounts of "unknown"are available.


  • Every other characterization procedure has been
    completed.


  • Example: In oxygen, carbon and sulfur analysis
    at least a few grams, and possibly more, may be needed
    to obtain good statistics on oxides, sulfides, carbides.



  • Advanced, but expensive, equipment becoming available
    to do destructive analysis on particles, e.g., milligrams
    of materials.
