The near-infrared laser Raman spectra influenced by environmental light were studied in the determination of sodium glutamic acid solution. The environmental lights included natural light from outdoors and light from room fluorescent lamp. The results show that different influences on near infrared laser Raman spectra of sodium glutamic acid solution can be produced in different environmental light. There were some characteristic spectral lines, down peaks or sharpened peaks. These influences cannot be ignored. It is suggested that the determination of solution by near-infrared laser Raman spectra is carried out in dark-room or in dark cover to completely isolates the influences of the environment lights.
