A novel spectroscopic imaging approach has been developed for parallel analysis of ionic liquids under controlled environment. Spectroscopic imaging is based on the use of infrared array detector for measuring spectra from different locations in a sample. This approach also allows to simultaneously acquiring spectra of many samples arranged in a patterned grid on the surface of the crystal in the ATR spectroscopic cell. This approach was combined with a device that controls humidity inside the cell. It was possible to obtain “chemical snapshots” from a spatially-defined array of many samples of different ionic liquids under identical conditions. Simultaneous response (for example water or organic solvent sorption) of the array of samples of ionic liquids to the environmental parameters was studied. This high-throughput imaging approach will be of great value in the area of ionic liquids research where the number of newly synthesised ionic liquids is growing rapidly.
