Terahertz time-domain spectroscopy technique for rapid qualitative detection of melamine in milk powder

73THz, average refractive index of 2.18. Were also calculated using DFT results consistent with the experimental data. In the experimental range of melamine in 1.62THz3. , 3ergFm8642O4 tank of 134 College of Volume 20 of the absorption peak corresponding to the molecular vibration of the lattice vibration. The results for the use of THz time-domain spectroscopy for the determination of melamine in milk powder that provides the initial basis for recognition; In addition, research also shows THz technology in the field of milk quality and safety of potential applications. This article is measured and mixed with high content of pure melamine milk powder samples, to realize THz-TDS based on a mixture of trace detection of milk need to be further carried out.
