Analysis of Aqueous Solutions

Infrared spectroscopy can be used for the analysis of aqueous solutions.

IR-Spectroscopy is not limited to gases and solid material, but does also facilitate to measure substances in aqueous medium. Due to the strong and temperature dependent absorption of water, the usage of conventional IR-transmission and ATR accessories were not very suitable for the analysis in water. CONFOCHECK™ is a new FT-IR system equipped with dedicated accessories allowing fast, easy and sensitive analyses of aqueous samples. Using this system, preparing, measuring and evaluating any aqueous sample takes typically about 1 minute.

On the basis of an IR spectrum, the sample can be identified and its components can be quantified. By comparing the sample spectrum with the spectra of a reference library, the sample in question can be identified unambiguously. Moreover, sample compositions that deviate from the reference or sample contaminations can be detected and evaluated. (See figure 1.)
