1.Product profile

  The MP-800S handheld high-frequency surface swept Raman spectrometer adopts transmission body phase grating (VPG), spatial direct coupling and confocal technology to realize small volume and large flux Raman signal acquisition, and the sensitivity is 10 times that of traditional Raman equipment. At the same time, digital microscopy technology is used to make the laser no longer gather at a fixed point, but constantly move according to the pre-defined trajectory, which breakthrough solves the technical problems such as excessive focus energy, easy damage and even ignition, and expands the application field of Raman technology. The surface scanning technology in the controllable area can measure the average spectrum of the whole surface, and solves the problem of mixture measurement deviation and suspicious object leakage detection. In this mode, the enhanced detection of more than 10 mixtures can be realized, and the surface contamination distribution of chemical poisons or explosives can be more accurately analyzed. The total amount of material spectrum database is more than 10000, and can be expanded according to the needs to meet the requirements of users.

  Mainly used to carry out emergency accidents of chemical agent rapid detection, explosive, inflammable and explosive and other toxic and harmful substances rapid analysis, temporary safety inspection and explosive and explosive material detection tasks, can also be used in complex environment of unknown solid, powder, liquid analysis, drug identification and analysis, dark material detection and multi-component mixture detection, police drug identification, etc.
