Abstract :
[en] The feasibility of rapid quantitative analysis of coal by Laser—Induced Breakdown
Spectroscopy technique was studied．The calibration curve method for LIBS quantitative analysis is introduced．Five coal samples were selected as investigation subjects，the carbon plasma line
of 505．2 nm was chosen as analysis spectrum line，and the carbon content of coal was analyzed quantitatively with delay of 0．8us， 1．2us， 1．6 us， 2．0 us and 2．4us． The results were compared with the results measured with Element Analysis Instrument．The error measured in1．6us delay was the minimum ，the effect of delay time on the quantitative analysis was analyzed．The results indicate that LIBS has a great potential in fast analysis of coal content．
