Chemical & Element Maps


Chemical and elemental mapping are methods that use advanced element or chemical analysis tools that directly characterize the chemical or elemental content of a surface, near-surface, bulk or exposed interior of a sample or product.

Chemical states, molecular species and elements cannot be seen by the human eye or imaging microscope tools that use light, electrons or ions.

The lateral distribution (homogeneity) of chemical states, elemental, inorganic, molecular species can be revealed by using:

    • Electrons (in eV) emitted & mapped by XPS
    • Infrared light emitted & mapped by FT-IR Spectroscopy
    • Laser light emitted & mapped by Raman Spectroscopy
    • X-rays emitted & mapped by EDS attached to SEM, FIB-SEM, TEM, STEM

Chemical, molecular and element mapping methods provide maps (images) that reveal the relative positions of different elements, chemical states or chemical species of interest.

Techniques for Chemical and Element Mapping:

Top Surface for Chemistry or Elements  (1-12 nm)


Near-Surface for Elements  (0.5-3.0 µ)


Elements at the Atomic or Nano-Scale – After Exposing


Bulk Region for Chemical Compound or Molecular Species
