N2 - Laser-induced breakdown spectroscopy is a technology that can be used for high-speed, real time, multi-component, online, remote detection, and it has considerable superiority in explosives detection. In the present experiment, using 1064 nm Q-switch laser beam as the resource, the authors investigated a common inorganic explosive (black powder) and one of its key components (KNO 3), while choosing NaNO 3 as the reference. We obtained the LIBS spectroscopy of these three samples in two surrounding atmospheres (air and Ar gas) at different time delay. And we analysed the change in line intensity ratio of N, O along with the increase in time delay, and found that the maximum of the value of O/N is obtained at time delay 596 ns.
