✦ Synopsis

Flow injection (FI) sample introduction was used in microwave plasma torch atomic emission spectrometry (MPT-AES). An FI in conjunction with a pneumatic nebulizer was evaluated. The effects of microwave forward power, flow rate of support gas and carrier gas, HCl concentration in sample solution, sample-loop volume, and some easily ionized elements (EIEs) on emission intensity were examined in detail. Selected elements were determined by FI-MPT-AES. The experimental results shown in this paper indicate that the effect of easily ionized elements (EIE) can be reduced and the analytical performance of MPT-AES using and FI sample introduction system is promising.

A method was developed for simultaneous preconcentration and on-line determination of 15 transition metals (Ag, Au, Cd, Cr, Cu, Fe, In, Ni, Pb, Pd, Pt, Ti, Tl, V, Zn). A polyetherether-ketone (PEEK) loop as preconcentration unit introduced by us earlier was used for the multielement flow injection (
