Phase behaviour of stearic acid-triethanolamine soap on the Specac Heated Puck for Quest: a literature replication study

Specac have shown that the Quest ATR Heated Puck, allied to the functionality of the Temperature Controller software, is a powerful system for collecting high quality spectra at a range of temperatures. Direct spectrometer control allowed the experiment to be fully automated except for sample loading. Detailed analysis of the temperature-induced changes in the spectra can be used to obtain insights into the phase behaviour of mixtures such as the soaps described here. Finally, use of blank spectra to control for changes in the diamond phonon mode changes proved superior to the use of a blank temperature background and is strongly recommended.
