[Influence of different light source on the laser Raman spectra in determination of sodium glutamic acid].
The influences of different laser source and different light power on laser Raman spectra were studied for the sodium glutamic acid. The results show that some influences existed using different wavelength and power of light source the peak shifting 6 cm(-1). As UV laser has great light power, the samples were destroyed, making the Raman spectra- reduce or disappear. The attenuation of light was needed. The linear relation existed between the Raman intensity and the power of laser light source, and the correlation coefficient was more then 0.999. The Raman intensity per light power unit was related to the wavelength, and was not related to the power of laser source.
