Daten: 10004017, ICP-19: Application of Prominent Spectral Lines for ICP-OES in the 125-190 nm Range
Kurz: Spectral lines for ICP-OES in the vacuum UV range between 125 and 190 nm have been found essential for a range of applications. The following main reasons can be named. 1. Many elements, such as Al, As, Br, Cl, C, Ga, Ge, Hg, I, In, N, P, Pb, Pt, S, Sn and Tl, have their most intense emission lines in the wavelength range 125-190 nm giving higher signal to background ratios compared to lines above 190 nm. 2. Because of a lower abundance of emission lines from the transition elements (Fe, Mn, Cr, etc.), spectral lines below 190 nm are mostly free from spectral interferences. 3. Less intense VUV lines are often useful for the determination of elements with higher concentrations, thus avoiding dilution. 4. A greater flexibility in the spectral line selection is provided.
