The technique of the direct analysis of zinc solid samples by two-jet arc plasma optical emission spectrometry
(TJP-OES) with electrothermal vaporization (ETV) of samples is developed. Vaporization of sample matrix (zinc)
and analytes from graphite tube during different temperature programs is investigated. The matrix influences
from zinc on the signals of analytes are studied in detail. It has been shown that the simultaneous vaporization of
analytes and sample matrix makes it possible to determine the content of the largest number of analytes elements
with insignificant matrix effects. The results of optimization of instrumental parameters of TJP-OES analysis are
presented. The technique of direct ETV-TJP-OES analysis of zinc provides limits of detection (LODs) of Ag, Al,
Au, B, Ba, Be, Ca, Co, Cr, Fe, Ga, Mg, Mn, Ni, Re, Sn and Sr from 0.05 to 100 ng g 1. Due to the high efficiency of
ETV for the sample introduction the LODs of most analytes were improved from 2 to 20 times comparing to the
TJP-OES with standard sample introduction system.
