Applications: Characterization of liquids and films in the range 175-900 nm, and also powders by means of a diffuse reflectance accessory (DRA) in the range 300-800 nm. This device can be setup for performing reflectance, transmittance or absorbance measurements of diffuse, specular, or mixed samples, not only powders, but also other highly diffractive samples, like nanoparticles dispersions, rough films and surfaces, etc. A liquid cell holder can be setup for performing variable temperature experiments using a thermostatic bath circulator.
Available objectives: Applications: Characterization of specific spots in solid samples (films, coatings, powders, textiles, etc.). The automatization of the stage allows for the obtaining of chemical mappings of large regions. Visible and infrared polarizers are available.

Applications: PM-IRRAS allows for the high-sensitivity analysis of ultrathin layers and coatings, monolayers and submonolayers and biomolecules, deposited on surfaces, especially conducting ones (Au, Cu, Pd, alloys, etc). It provides information, not only about the composition of the deposited materials, but also about their organization, conformation and orientation. Thanks to the characteristics of PM-IRRAS, samples can be measured without a reference and the yielded spectra are free from atmospheric interferences, such as carbon dioxide and water vapour. VCD is a technique that provides 3D...
Applications: Static and dynamic contact angle Surface free energy of solids. Surface and interfacial tension of liquids. Advancing and receding contact angles and evaluation of a roll off angle by tilting table method. The DSA25S features a high speed camera with a resolution of, at least, 1920 x 1200 px, and an automatic software-controlled dispenser and tilting stage.
