MS650 Laser Raman spectroscopy drug detector is a security inspection instrument for anti-terrorism, drug control and epidemic prevention. It is used for Raman spectrum detection of explosives, drugs, precursor chemicals, alcohol and psychotropic drugs in various forms such as liquid, solid, powder and aqueous solution. The equipment adopts the most advanced laser Raman spectroscopy analysis method, integrating sampling, detection, spectrum scanning and processing, database search, similarity comparison and recognition. It is easy and fast to operate, and automatically calibrates when it is turned on. The handheld laser Raman spectrometer is small in size, light in weight, easy to carry, simple to operate, and can accurately and quickly detect and analyze the composition of substances.
