Laser-Raman spectrum for detecting benzene

A new method is proposed for detecting the concentration of benzene quickly and accurately with Raman spectrum. Based on the theoretical analysis of benzenes Raman spectrum, the experiments proved that the Raman spectrum peak value of benzene was proportional to the concentration of benzene, which could be obtained by substituting the strongest peak value of 561.4nm into the linear regression equation, with the detection limit of 0.3%.
