Calibration-free(CF)laser-induced breakdown spectroscopy(LIBS)is normally only applicable for gated detectors due to its dependence on the assumption of a steady-state ***,most currently available LIBS systems are equipped with non-gated detectors such as chargecoupled device(CCD),which degrades the accuracy of CF *** this paper,the reason for the less satisfactory quantification performance of CF for LIBS with non-gated detectors was clarified and a time-integration calibration-free(TICF)model was proposed for applications with non-gated *** was based on an assumed temporal profile of plasma properties,including temperature and electron density,obtained from another *** line intensity at different time during the signal collection time window was estimated with self-absorption correction according to the temporal profile of the plasma *** proposed model was validated on titanium alloys and compared with traditional *** accuracy of elemental concentration measurement was improved significantly:the average relative error of aluminum and vanadium decreased from 6.07%and 22.34%to 2.01%and 1.92%,*** quantification results showed that TICF method was able to extend the applicability of CF to LIBS with non-gated detectors.
