A new rapid analyzer from the series of approved 1TRA devices as developed in the Research Institute of Non-Ferrous Metals Freiberg for single- and multielement analysis in non-ferrous metallurgy is described. ITBA-084 represents an efficient microprocessor-controlled on-line analyzer on the main principles utilized hitherto with success in device engineering (isotope excitation, four-channel modification, balance filter method). A monoboard microcomputer based on U880 provides the central control of the device, allowing extensive analytical programs for matrix correction to be executed. High stability and reproducibility of measured values are achieved by the use of digital peak stabilization. Scintillation probes and proportional counters are used for the detectors. The efficiency of the analyzer is demonstrated and discussed in the light of measured values.
