Identification of molecules in graphite furnace by laser ionization time-of-flight mass spectrometry: sulfur and chlorine containing compounds

Atomic spectrometry update. Atomic mass spectrometry

“…The molecular form of the gas phase species generated by ETV was determined using TOFMS and ionization by a dye laser (l ¼ 219 and 240 nm) or a frequency quadrupled Nd:YAG laser (l ¼ 266 nm). 249 Upon heating H 2 SO 4 or MgSO 4 and irradiating at a l of 219 nm, S 1 and SO 2 1 ions were observed whereas only SO 2 1 ions were seen using a l of 266 nm. Vaporization of sulfur yielded signals of S 1 and S 2 1 at l of 219 and 266 nm.…”
