- Аннотация: We propose what we believe to be a new approach for elemental analysis using laser induced breakdown spectroscopy (LIBS). This method offers enhanced convenience and simplicity for elemental analysis as it eliminates the necessity of Boltzmann/ Saha-Boltzmann plot. It is an intensity-ratio based approach that provides several notable advantages. One of the key benefits is its ability to perform comprehensive elemental analysis using only a few spectral lines; specifically, only n + 1 emission lines are sufficient for a sample containing n elementalspecies. This offers a great flexibility in the choice of emission lines which do not suffer fromself-absorption. Further, high accuracy can be obtained as many repeated estimations from a single measurement are possible. We demonstrate the theory and working procedure of this technique by experimentally recording the data of two samples (binary and ternary copper alloys). A nanosecond Nd:YAG pulsed laser of ∼7 ns pulse duration and 532 nm incident wavelength is used. The results are in good agreement with CF-LIBS and Energy-dispersive X-ray spectroscopy (EDS).
