Monolayer/Grazing Angle Specular Reflectance Accessory - 1

Reflectance I Monolayer Grazing Angle Accessory A dual purpose sampling device to provide the means on in-situ FTIR investigation of films at an air or liquid interface and grazing incidence angle measurements of the thin film coatings on solid reflective surfaces The Monolayer / Grazing Angle Accessory allows the study of insoluble monolayer films at air-water interface in-situ using an MCT or InSb detector, and also the analysis of reflective surfaces at grazing incidence angle (8° - 85°) using a standard DTGS detector. Alignment is very easy, as it involves the adjustment of only two mirrors. Conversion from one form to another is achieved by a simple change of sample holders. In monolayer mode, a variety of monolayer systems (eg. durfacants, proteins, steroids, polymers and phospholipids in biological membranes) can be studied in their native environments. The ability to stretch and compress the films is incorporated, and useful information such as phase transition changes, solvation of head group, orientation of hydrophobic chain, conformation, configuration and polarization studies may be made. Operating in the grazing incidence mode at high angles of incidence, upto 85°, allows analysis of thin layers of Langmuir-Blodgett films absorbed on reflective surfaces. Aperture stops are provided to redefine the the beam profile to be at prime position on samples at or near grazing angle to enhance the performance data of semi-conductor materials and films can be evaluated.
