Atomization of Organic Compounds in the Inductively Coupled Plasma

Volume 42, Number 4 (June 1988) Page 595-598

Hauser, P.C.; Blades, M.W.


The problem of incomplete atomization when nonmetals are being determined in aspirated organic solutions was studied. Abel inverted spatial profiles of C2, CN, C(I) and S(I) emission were acquired at several heights. It was found that molecular emission caused by the analyte is restricted to the lower aerosol channel. Nonmetal atomic emission is found in the toroidal region and higher up in the aerosol channel. Compounds that contained nonmetals comprised of either oxygen, nitrogen, or sulfur, which were dissolved in xylene, exhibited nonmetal emission intensities independent of the structure of the compound.
