Selective Filtration in Optical Emission Spectroscopy

  • Andrew Szule

Abstract

Determination of the most common elements by optical emission spectroscopy ordinarily requires two analyses. The first analysis is run in the 2300 to 3500 Å uv range using a grating properly blazed to this range that has high linear dispersion. The second analysis is performed where the most sensitive lines of the alkali and alkaline-earth elements occur. In this case, another grating, blazed to higher wave-length regions in the visible range, is required. Because of the wide spread of the lines, this grating must cover a wide range (4000 to 8800 Å); therefore, a low dispersion grating, such as one with 300 lines/mm, was selected. The total coverage of this grating is 4800 Å on two 4- x 10-in. photographic plates.
