Q:
What are some important issues for
any Characterization technique?




A:

  • Define Resolution and Accuracy
    For microscopy and chemical analysis
    Determine Lower detection limits
    Maximum limits - what you need -vs- what is available
    Especially important for chemical techniques


  • Sample gathering and preparation techniques
    may affect data generated

    Begin with nondestructive microscopy
    Finish with destructive chemical analysis, if necessary
    Especially important for corrosion applications


  • Logical Technique Series
    Usually proceeds from less expensive to more
    expensive to hold costs down, and is need based
