Analysis of egg using thermal ATR

Thermal ATR is a real time procedure for analyzing the vibrational structure of molecules using temperatures that range from room temperature to approximately 80°C. Procedures such as Differential Scanning Calorimetery (DSC) are commonly used to analyze solid samples; however, thermal ATR is more effective than DSC for analyzing liquid samples. Furthermore, although thermal analysis of water content is used in the field of food analysis, monitoring the vibrational structure of samples directly is usually not possible with methods other than ATR.

The following is an example of thermal ATR analysis performed on egg, for which water content is approximately 75%.
