Raman spectra of drop coating deposition Raman for melamine solution

Melamine is an organic compound that is often combined with formaldehyde (chemical compound) to produce melamine resin, a synthetic polymer that is fire resistant and heat tolerant. Melamine can be easily molded while warm but will set into a fixed form, which makes it suitable for certain industrial applications. This compound is considered safe for its normal uses, but food products that are contaminated with it can be unsafe for consumption. Routine consumption can cause acute renal failure, kidneys damage and death. Focusing on the milk with melamine in the market, a rapid and easy method is needed to detect melamine from the milk. Now with Surface Enhanced Raman Spectroscopy (SERS), which is capable of detection up to a single molecule, this problem can be surmounted. This paper describes the characterization of dried melamine sample prepared via drop coating deposition Raman (DCDR) method for Raman analysis. Two chosen substrates were used for sample deposition. The samples were analyzed using Dispersive Raman Spectrometer to observe the Raman spectra for different concentration of diluted melamine solution. Using statistical analysis, our results demonstrate that the melamine peak intensity is linearly proportional to the melamine solution concentration. In addition, the SERS detection method proves to be a fast, highly sensitive and quantitative detection for melamine.
