Analysis of Minor Components in Water Using the IRSpirit
10 Feb 2019Water absorbs strongly in the mid-infrared region, which makes it difficult to detect and identify solutes in low concentration aqueous solutions. The water bands simply overwhelm spectral contributions of minor components. Several processing and sampling techniques have been developed to get around this issue. For meaningful results however, these methods require both stability and sensitivity of the FTIR instrument.
This article describes a difference spectrum method and sample condensation technique using the compact IRSpirit, a stable and sensitive compact FTIR instrument.

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses.
