The invention provides a trace ammunition detector and a detection method. The trace ammunition detector comprises an air pumping module, a trace ammunition detection module, a metal sol injection module, a laser emission module, a Raman analyzer and a data analysis and display module. The trace ammunition detection module is internally provided with at least one micro-channel, the metal sol injection module injects metal sol into the micro-channel, the air pumping module conveys to-be-detected air into the micro-channel, the metal sol reacts with the to-be-detected air in the micro-channel, the laser emitted by the laser emission module irradiates the metal sol in the micro-channel to generate a Raman scattering spectrum, transmitting the spectrum data to the data analysis and display module by the Raman analyzer, carrying out analysis and treatment on the Raman scattering spectrum to obtain whether to-be-detected air contains trace ammunition, and determining the ammunition type under the circumstance of trace ammunition. The trace ammunition detector provided by the invention has the advantages of high integration degree, high sensitivity, high precision, light weight and reliability, easy operation and the like.
