SERDS Raman Spectrometer
application
ATR3020 can reject the fluorescence by shifted excitation Raman difference spectroscopy, The ondition of 1nm wavelength difference, The Raman signal is very sensitive to the excitation wavelength difference, but the fluorescence signal is not sensitive to it. The differential technology can be used to suppress the fluorescence. It can directly measure high fluorescent substances, anti-interference, anti noise, greatly improve the detection sensitivity and signal-to-noise ratio 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.
Because it can remove all kinds of interferences such as fluorescence, ATR3020 portable Raman spectrometer can not only ensure the accuracy, but also reduce the requirement of light source power, improve the reliability of the whole instrument and the ability of spectrum fault tolerance and error correction. Combined with SERS technology, ppb level detection capability can be achieved, which is suitable for field operation. ATR3020 also has significant reliability, which makes the test results accurate and reliable.
The excellent low stray light condition makes the spectrometer widely used, especially in biochemical analyzer, food safety, pharmaceutical engineering and so on. The multifunctional software promotes the spectral analysis process in application. The remote experiment through Internet access makes the test project easier.
