A method and apparatus for inspection of liquids are disclosed. The method includes inspecting a liquid with a technique selected according to whether the package of the liquid is transparent, semi-transparent or opaque. If the package is transparent or semi-transparent, Raman spectra technique is used; if the package is opaque, a technique using electronic scale and barcode reader is used. In some embodiments, the Raman spectra technique and the technique using barcode reader and electronic scale can be used independently for inspection of the liquid. The inspection apparatus according to the present disclosure has advantages, such as capability of material identification, rapid examination speed, small volume, light weight, portability, low cost, free of radiation, and simple maintenance. The method and apparatus according to the present disclosure are suitable for safety inspection in public places having large number and fast flow of people. |
