“…The UV background spectrum emitted by the low power and low Ar consumption µCCP consists of molecular emission from NO (A 2 Σ + →X 2 Π; E ex = 5.45 eV; 205.28 nm (2,2); 215.49 (9,1); 226.94 nm (0,0); 237.02 nm (1,0); 247.87 nm (2,0); 250.60 nm (5,0)) and OH (A 2 Σ + →X 2 Π; E ex = 4.05 eV; 269.11 nm (1,3); 282.90 (0,1); 289.27 nm (1,2); 296.24 nm (2,3); and 308.90 nm (0,0)). In a recent study aiming to determine total Hg and CH 3 Hg + in food and river sediment by SSETV-µCCP-OES, it was remarked the capability of microplasma to provide several emission lines of Fe, S, and P in the range 180–200 nm [ 67 ]. In another study on the simultaneous determination of Ag, As, Cd, Cu, Hg, Pb, Sn, and Zn in soil, it was achieved a selective vaporization of Hg and Ag at 1200–1300 °C, while for the less volatile elements such as Cu and Zn, it was necessary a vaporization temperature of at least 1500 °C [ 66 ].…”
