Uses variable angle capabilities for interface analysis by specular reflectance

Highlights

• Grazing angle capability
• Monolayer analysis
• Continuously variable incidence angles from 8º - 85º (dependant on spectrometer)
• Volume of trough 8.9 ml
• Sample size 50x20 mm
• Built-in polarizer mount
• Aperture stop facility for controlling the sampled area
• Liquid film compression/ expansion capability
• Inert Teflon sample trough (liquids)

Applications

• Reflection-absorption spectra of solids
• Langmuir-Blodgett films
• Surfactant studies
• Liquids in biological membranes
• Semi-conductors
• Paints
• Resins
• Polymer coatings
• Matt surfaced samples
• Molecular orientation of surfaces

Information
The Monolayer/Grazing Angle accessory allows reflectance measurements to be made on a variety of samples over a wide range of angles of incidence. Solid samples can be placed on the flat stage or liquid samples can be poured into the Teflon Monolayer trough. This has a moveable liquid surface tensioning boom to allow the study of orientated mono-molecular films on a liquid surface.
