Optimal Observation

A comparison of an “end-on” viewed argon inductively coupled plasma (ICP) operated in the horizontal position with the conventional “side-on” viewed argon ICP was carried out using the same experimental setup. The end-on ICP required an air cutoff stream located toward the tip of the luminous discharge, to protect the optics and to increase linearity ranges, and the orifice diameter of the central tube of the torch was widened to 1.9 mm, to improve line/background ratios. With the end-on viewed plasma the linearity ranges, the susceptibility to solute vaporization and to ionization matrix effects, and the detection limits in an organic solvent were insignificantly different from those observed with the side-on viewed plasma. Detection limits with aqueous samples were always significantly lower with the end-on viewed plasma, usually five- to tenfold lower, in a few instances, 20-fold lower. With the end-on viewed plasma the optimal observation region for both single and simultaneous multielement analysis is one and the same and is extremely easy to locate.

Abstract Using a spectrometer with an argon plasma source coupled to a high-frequency magnetic field, we developed a direct method for determining iron in urine of patients being treated with deferoxamine. The detection limit for iron was 75 nmol/L; added iron was satisfactorily recovered; and we observed no interference from deferoxamine at its most commonly used concentrations. Values for between-run and within-run precision (CV) was less than 5%. Correlation of results with those obtained with a colorimetric method involving bathophenanthroline was good (r = 0.96).
