Fourier transform infrared spectroscopy of aqueous solutions using
... Reduction of signal dynamic range and prevention of detector saturation may be obtained by filtering out light in spectral regions that contain no usable signal. For aqueous transmission spectroscopy, the choice of pathlength effectively selects a narrow spectral region with a high SNR such that oth ...
