The argon inductively coupled plasma (ICP) is presented as an excitation source for near infrared atomic emission of nonmetals. Wavelength and relative ICP intensity listings are presented for atomic nitrogen and atomic fluorine emissions. A gaseous sample modulation system is described which assists in the characterization of the ICP as an excitation source for near infrared emissions of nonmetals. Vertical profiles of O(I), F(I), N(I), C(I), and S(I) emission are presented for gaseous samples. The effects of atmospheric entrainment on quenching and contamination are studied, and the use of an extended ICP torch is discussed. The use of the ICP as an oxygen- and nitrogen-selective detector for gas-liquid chromatography is reported. Molecular formula determination utilizing the ICP excited near infrared atomic emission of nonmetals and photodiode array detection for multichannel response is introduced. Solution phase sample introduction to the ICP for nonmetal detection is shown to be feasible with electrothermal atomization, although quantitative results are not reported. The Babington nebulizer is used to qualitatively determine sulfur in a 10% coal slurry and fuel oil samples. Interferences from As, Se, Ni, Cu, NO/sub 3//sup -/, and BH/sub 3/CN/sup -/ are discussed.
