The invention discloses a laser dual-mode microvolume sample analyzing method based on laser thermal lens and laser retroreflection interference technique and the used device. Under the wavelength of the used laser, test the signal of the substance with light adsorbing characteristic by the laser thermal lens testing mode to each component through liquid phase separation, and test the signal of the substance without fluorescent and light adsorbing characteristic by the laser retroreflection interference test mode. The invention doesn't need to conduct any sample deriving and collecting processing procedures. Because the required checking sample poor is micro-checking pool, the needed sample volume is very small and can reach nano flow at lowest. The used device in the invention is simple to operate, which has low daily maintaining fee, quick testing speed and accurate result, and can be widely used in the characterization and quantification testing to the need checking system including various different chemical substances.
