The working principle of the laser induced breakdown spectroscopy (LIBS) is introduced.How the atmosphere interferes in the LIBS result of the solid samples is interpreted by expatiating the physical principle of generating the plasma spectrum.A LIBS experimental system for the low pressure condition was setup and the convenient experiments at the low pressures were carried out.The possibility of the interferer from the atmosphere is testified.The feasibility of the idea carrying on LIBS experiment at low pressure to overcome atmosphere interfere is validated.
