Raman spectroscopy method to eliminate inter-station difference

The present invention relates to a difference between the Raman spectroscopy method to eliminate station, comprising: 1) the accuracy of the wave number, wave number accuracy, SNR, relative peak intensities of these four quantization index, Raman spectroscopy of the inter-stage quantized difference achieved characterization; 2) X-axis alignment, baseline shift correction, the relative intensity correction, inter-Raman spectrometer difference control station. The present invention shows how to achieve a difference between the quantization of the characterization and control station Raman spectrometer, so as to eliminate the inter-stage Raman difference object, functions between the performance and stability of control instruments, in order to further achieve according to the need to establish a stable detection by Raman spectroscopy mathematical model and implement the transfer model, specific broad application prospects.
