“…However, a major difficulty for wavelengths below 180 nm is that radiation is absorbed by components of air, such as oxygen or water vapor. Approaches to overcome this problem are to flush the spectrometer with an inert gas or to evacuate the optical system [1,2,3,4,5,6,7,8,9,10]. Kirkbright et al [1,2], who were first to propose VUV spectral lines, purged the monochromator and the optical path between the plasma torch and the entrance slit with nitrogen.…”

“…Kirkbright et al [1,2], who were first to propose VUV spectral lines, purged the monochromator and the optical path between the plasma torch and the entrance slit with nitrogen. Later, other authors [3,4,5,6,7,8,9,10] purged the spectrometer with helium, nitrogen or argon or evacuated the spectrometer in order to study VUV spectral lines. La Freniere et al [7] used a helium purged monochromator and published a list of atom and ion lines for ICP-OES in the range from 115 to 295 nm, detected through an optical sampling orifice inserted directly into the ICP.…”

A new axially viewed ICP optical emission spectrometer featuring an argon-filled optic and CCD detectors was evaluated for the application of prominent spectral lines in the 125-180 nm range. This wavelength range was investigated for several analytical applications of inductively coupled plasma optical emission spectrometry (ICP-OES). There are different advantages for the application of spectral lines below 180 nm. A number of elements, such as Al, Br, Cl, Ga, Ge, I, In, N, P, Pb, Pt, S and Te, were found to have the most intense spectral lines in the wavelength range from 125-180 nm. Compared with lines above 180 nm higher signal-to-background ratios were found. Low limits of detection using pneumatic nebulization of aqueous solutions for sample introduction were calculated for Al II 167.080 nm (0.04 microg L(-1)), Br I 154.065 nm (9 microg L(-1)), Cl I 134.724 nm (19 microg L(-1)), Ga II 141.444 nm (0.8 microg L(-1)), Ge II 164.919 nm (1.3 microg L(-1)), II 142.549 nm (13 microg L(-1)), In II 158.583 nm (0.2 microg L(-1)), P I 177.500 nm (0.9 microg L(-1)), Pb II 168.215 nm (1.5 microg L(-1)), Pt II 177.709 nm (2.6 microg L(-1)), S I 180.731 nm (1.9 microg L(-1)) and Te I 170.00 nm (4.6 microg L(-1)). Numerous application examples for the use of those lines and other important spectral lines below 180 nm are given. Because of fewer emission lines from transition elements, such as Fe, Co, Cr, lines below 180 nm often offer freedom from spectral interferences. Additional lines of lower intensity for the determination of higher elemental concentrations are also available in the vacuum ultraviolet spectral range. This is specially useful when the concentrations are not in the linear range of calibration curves obtained with commonly used lines.

“…In a number of papers or wavelength tables dealing with arc, spark, or ICP optical emission spectrometry spectral lines in the wavelength region below 190 nm are mentioned. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] A problem, however, is that radiation at wavelengths below 190 nm is absorbed by components of air, primarily oxygen or water vapor. Therefore, the use of VUV spectral lines for plasma optical emission spectrometry has been studied with different kinds of spectrometers.…”

“…In contrast to the ion lines, Heine et al 5 reported several atom lines of O, N, C, Br, S, and Cl in the VUV range with a vacuum spectrometer that was purged with helium in the optical path. Hayakawa et al 6 studied the use of VUV lines for the determination of P and B in iron and steel and for the determination of I, B, and S in sea water.…”

It is shown that the use of analytical lines in the spectral range between 125 and 195 nm opens new analytical possibilities for inductively coupled plasma optical emission spectrometry (ICP-OES). Prominent emission lines in the vacuum ultraviolet (VUV) spectral region were used for different analytical applications with a new ICP optical emission spectrometer with charge-coupled device detectors (CCDs). These applications include the determination of Cl and S in organic samples (oil and gasoline), the determination of Al, Br, I, and P in high-saline 200 g/L NaCl solutions, and the determination of Pb, Sn, and In in highly pure 99.9% (m/m) Pd and Pt. The superiority of the VUV emission lines of Al 167, Br 148, Cl 134, Cl 135, Ga 141, I 161, In 158, P 177, Pb 168, Sn 140, and Sn 147 nm in these applications with respect to power of detection and freedom from spectral interferences is shown. The limits of detection (LODs) are tabulated for a series of further elements with prominent spectral lines in the 125–195 nm range using pneumatic nebulization of aqueous solutions for sample introduction. These results are compared with those for lines above 195 nm. In some cases VUV lines are superior to commonly used lines; for example, calculated LODs for Al(II) 167.080 nm, In(II) 158.637 nm, and Ga(II) 141.444 nm are 0.07, 0.2, and 0.8 μg/L, respectively, compared to 1.1, 7.1, and 5.9 μg/L for Al(I) 396.152, In(I) 230.606, and Ga I 417.204 nm, respectively. In other cases LODs in the μg/L range are possible only with VUV lines, such as for Cl(I) 134.724 or Br(I) 154.065 nm.
