IR-spektroskopische Untersuchungen wäßriger Lösungen mit Hilfe der ATR-Technik

The ATR-method is qualified for measuring aqueous solutions if the multiplereflection technique is used in such a way that strong water absorptions do not cover a large part of the information on the spectrum. The single-reflection technique is mainly suitable for solutions of 2-molar and higher concentrations. Organic acids, phenols, amides, saccharides and anorganic compounds had been measured. A practical example proved that there is the possibility of also taking quantitative measurements with the ATR-method.
