AES Theory: Limitations of AES

Although widely useful, AES does have limitations. It cannot detect hydrogen or helium. It does not provide for nondestructive depth profiles. It requires that samples be small and compatible with high vacuum. Nonconducting samples sometimes charge under electron beam bombardment and simply canít be analyzed. Elemental quantitation by AES depends on instrumental, chemical, and sample related factors.
