Abstract
It has recently been stated2 that “flame photometry can scarcely equal the freedom from spectral interference of atomic absorption until monochromators with effective band-passes of ca. 0.02 Å (i.e. half-band width of absorption line) become generally available.“ Resolution of at least this order is now attainable with the aid of instrumentation based on the echelle grating, with none of the disadvantages normally associated with conventional ultra-high resolution monochromators.
