Comparison of monochromators for wavelength-modulated atomic absorption and emission spectrometry

Continuum source atomic absorption spectrometry and detector technology: A historical perspective

“…Resonance lines for the elements Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Se, Sn, V and Zn could thus be recorded simultaneously, and the calculated absorbances were all shot noise limited. Similar systems were used by several groups for many fundamental [71][72][73][74][75][76][77][78][79][80][81][82][83][84] as well as applied [85][86][87][88][89][90][91][92][93][94][95] studies, and are also described in a number of overview papers [96][97][98][99][100]. In a detailed analysis [97], O'Haver and Messman stated that the undoubted advantages, in particular flexibility and excellent background correction, were unfortunately counterbalanced by the disadvantage that for elements with resonance lines at wavelengths shorter than 250 nm LODs were significantly poorer with CS AAS than with LS AAS.…”
