AES spectra were obtained from elements of the second row of the transition metals using a Perkin Elmer PHI 660 Scanning Auger Microprobe. Auger spectra were taken from Ag, Cd, In, Mo, Nb, Pd, Rh, Sb, Sn, Y, Zr, and Ru samples under identical conditions. Each elemental spectrum was obtained with electron beam energies of 3, 5, 10, and 20 keV using a 1μA beam current. These parameters yield spectra which could easily be obtained under normal operating conditions (for comparison). These conditions are easily obtained by other instruments. The Cu sample was also used to obtain data used in calculating the signal-to-noise ratio. The ratio was obtained using the primary CuKLLpeak located at 919 eV. The instrumental energy resolution used for all of these measurements was 0.61% ± 0.008% measured with a 3 keV backscattered peak.
