ATR3020 adopts the international leading Fluorescence Rejection By Shifted Excitation Raman Difference Spectroscopy (SERDS). In the shifted excitation, the Raman signal is very sensitive to the excitation, but the fluorescence signal is not sensitive. The differential technology is used to reject the fluorescence. It can directly measure high fluorescent substances, anti-interference, anti noise, improve the detection sensitivity and SNR of the whole system, filter out interference peaks (such as ambient light peak, fluorescence peak, etc.), retain only pure Raman peaks, and capture tiny signal difference.
