Аннотация:Luminescence spectra of several polarity indicators, including Coumarin 153 and coronene that were previously studied at room temperature and Nile Red and Pigment Red 179, were recorded at 20 and 120oC in solutions of liquid stationary phases of various polarities. The eff ect of temperature on the spectral parameters sensitive to the stationary phase polarity was estimated for these indicators. The prospects for estimating the polarity of stationaryliquid phases using luminescent methods at high temperatures was demonstrated.
