We propose here a highly-sensitive, compact Raman system for quantitative analysis of biological samples. The system consists of a semiconductor laser, spherical integration type of cell-holder, Raman shift bandpass filter, photodiode, multimeter and personal computer. It dose not have a spectrometer. Therefore, one can not measure a Raman spectrum by use of the above system, but it is superb for...
This paper demonstrates the potential of a newly devised near-infrared Raman system in quantitative analysis of metabolites in urine. By using the system, Raman spectra have been measured for urine to which glucose, acetone, urea, or creatine was added artificially, and for urine including the four components simultaneously. The concentrations of glucose, acetone, urea, and creatine in urine which...
