Choice of fluorescence wavelengths for the determination of trace amounts of chlorine by graphite furnace laser-excited molecular fluorescence spectrometry of indium monochloride

Element-specific determination of chlorine in gases by Laser-Induced-Breakdown-Spectroscopy (LIBS)

“…Enhanced emissions of copper halides arise from a higher volatility and consequent production of excited CuOH, CuO and CuH species, therefore pseudohalides give also a false positive test. To circumvent these problems either other diatomic molecules like InCl were utilized in combination with flame spectroscopy [28,29] or other approaches as laser-induced fluorescence in a graphite furnance [30][31][32] or molecular emission cavity analysis (MECA) [27,33,34].…”

Determination of non-metals via molecular absorption using high-resolution continuum source absorption spectrometry and graphite furnace atomization

“…AlCl, GaCl or InCl, can be used for the determination of Cl via molecular absorption. Apart from investigations using LEMOFS, 13,18,19 mainly conventional AA instrumentation in combination with a deuterium (D 2 ) 16,20 or H 2 lamp 21,22 as the continuum source was used, and most of the latter works were focused on the molecule AlCl. In this case even the use of an ordinary lead hollow cathode lamp is possible due to the coincidence of one of its emission lines with the wavelength position of the AlCl band head at 261.418 nm, as demonstrated in a work of Parvinen and Lajunen.…”

Atomic Absorption, Atomic Emission, and Flame Emission Spectrometry

“…Molecular fluorescence of MgF in a graphite furnace was used for the determination of F (223), and Cl was determined by the molecular fluorescence of InCl (312).…”

“…Applications of ETA-LEAFS included the determination of Bi (304,305), Co (306) and Pb (307) in seawater, Tl (308) and Pb (309) in natural water, Hg in soil digests (310), and As and Se in blood (311). Molecular fluorescence of MgF in a graphite furnace was used for the determination of F (223), and Cl was determined by the molecular fluorescence of InCl (312).…”
