A preferred embedment of the system and a method are provided utilizing Fourier Transform Infrared Spectrophotometer (FITR) for examination and analysis of materials on a real-time basis in a chamber at elevated temperatures with corrosive-erosive gaseous environments that cause accelerated material deterioration. The apparatus is capable on a real-time basis of examining and analyzing a wide variety of materials subjected to accelerated deterioration events missed by prior art systems and methods. Empirical data of accelerated corrosion-erosion events are also acquired and stored for subsequent computer analysis of recorded absorbed and reflected vibrational frequencies detected. The system utilizes preselected adjustable grazing angles of an incident beam of the infrared beam impinging upon a material sample during the observation and analysis processes to enhance the data to be collected. The system provides feed back laser signals for alignment adjustment for the selectable grazing angles.
