| Popis: | A spectral-kinetic recorder operating in a special time-gating mode was developed for time-shifted measurement of time-resolved spectra and emission-line intensity kinetics in atomic emission analysis. The luminescence intensity kinetics of Cu, Zn, Sn, and Pb were recorded for two-pulse laser ablation of pure metals and multicomponent alloys. The spectral-line intensity kinetics of pure metals could be approximated with high accuracy by exponential functions. The analytical signal for ablation of multicomponent samples decayed exponentially only for interpulse laser intervals |
