| titleOfInvention | Black powder pretreatment method |
| abstract | The invention discloses a pretreatment method of black powder and analogues thereof, which comprises the steps of treating the black powder and the analogues thereof by using a treatment fluid to obtain a sample fluid, using the sample fluid for laser excitation spectrum detection, and obtaining component detection conditions of the black powder and the analogues thereof through the detection of the sample fluid, wherein the use mode of the sample fluid comprises direct use, concentrated use or use after dropwise adding the sample fluid to a test piece to remove a solvent. The method can not only overcome the problem that the black powder and the like are inflammable, but also greatly enhance the laser excitation spectrum signal of the black powder, provide possibility for realizing safe and rapid detection of the black powder, have wide detection components and provide convenience for dangerous object investigation and identification work. |
