MULTIPURPOSE ATOMIC-IONIZATION SPECTROMETER - ANALYSIS OF HIGH-PURITYSUBSTANCES

The design and the analytical characteristics were described for the a tomic-ionization spectrometer that employs three types of atmospheric- pressure atomizers (flame, graphite furnace, and rod-flame combined sy stem) and provides direct analysis of liquid, powder, and solid sample s with detection limits to 10%. Analytical potentialities of the spect rometer are demonstrated by the determination of Li, K, Na, Sb, Cu, an d Ag in phosphoric acid, acetone, and isopropanol, as well as by the d etermination of Ni, Co, Cr, and Mn in fiber-optics fluoride materials, etc. as examples.
