Since the mid-90s, ionic liquids have become buzz words for many areas of science such as synthesis, electrochemistry, material science, separation technologies, and biocatalysis
Shimadzu Scientific Instruments has published the poster, 'Determination of Water in Room Temperature Ionic Liquid (RTILs) by Near-Infrared Spectroscopy'.
This presentation showcases the applicability of NIR spectroscopy for determining the absorbed water content in a commonly utilized ionic liquid.
Since the mid-90s, ionic liquids have become buzz words for many areas of science such as synthesis, electrochemistry, material science, separation technologies, and biocatalysis.
Chemists and engineers use both hydrophobic and hygroscopic ionic liquids in their research.
In the case of the latter, it is often crucial to determine and monitor the water content.
The high absorption coefficient of the hydroxyl (-OH) group in the near-infrared (NIR) region makes UV-vis-NIR analysers a logical instrument for accurate and reproducible moisture quantification.
In this presentation, Shimadzu's UV-3600 UV-vis-NIR spectrophotometer was used.
In addition to three detectors, which ensure high sensitivity over the entire measurement range and help achieve the world's lowest noise level with <0.00003Abs noise at 1500nm, the UV-3600 offers a number of other advantages that make NIR analysis an effective and efficient technique for analysis of moisture content in RTILs.
