Esperto: um sistema integrado para microanálises em sondas eletrônicas manuais a três espectrômetros

Abstract

An integrated software system, ESPERTO, has been developed for on-line acquisition and treatment of chemical data through microanalysis of materials by manual electron microprobe equiped with three spectrometers. The system comprises various programs written in BASIC and data archives that monitor the entire routine analytical procedure employed in the Electron Microprobe Laboratory of the Mineralogy and Petrology Department of the Geosciences Institute of the São Paulo University, which includes the following steps: collection of data, correction for experimental factors (background radlation, diift and dead-time of the counters) and empirical correctlons ("beta correctlon") for matrbc effects (atomic number, mass absorption, and secondary fluorescence).
