Application of Echelle Spectrographs to Quantitative Analysis of Boron in Steel

Determination of boron in glass by direct current plasma emission spectrometry

“…For the sample sizes and dilutions employed here, this level of interference is negligible except when boric oxide is low (less than 1%) and soluble iron is high (more than 15%) which necessitates the use of the 249.678-nm line. All other possible line interferences (21,27), including that of iron at 249.782 nm, are easily resolved by the echelle spectrometer. Continuum and banded emission can contribute to the line signal and could be significant when the analyte concentration is low.…”

Echelle Grating Spectrometers in Analytical Spectrometry

“…Some characteristics of the Margoshes system are shown in Table IV. The table gives, for several orders, the central wavelength, the dispersion, the resolution (controlled by the resolution of the vidicon), and the equivalent slit width that would have to be used to achieve this resolution on a conventional spectrometer with 5 A/mm dispersion. The dispersion and resolution are particularly good in the ultraviolet region of the spectrum.…”

Spectrographic Determination of Trace Quantities of Boron in Steel

“…Chem., 27, 1543 (1955). (6) Shyne, J. C., and Morgan, E. R., Metal Progr., 65, No. A quantitative spectrographic procedure has been devised for the determination of boron in steel within the range 0.0001 to 0.0006%.…”
