WebFeb 1, 2024 · Optical profilometry techniques are seen as an alternative to stylus profilometry methods, which use a physical probe to determine surface topography information. Optical methods offer several advantages over stylus-based tests. First, there is the possibility the stylus can deform the sample surface during testing, corrupting results. WebExtraction analysis is a method used to separate and isolate specific compounds or molecules from a sample matrix. This process involves using a solvent to extract the desired component from the sample. Once the component is extracted, it can be analyzed using various analytical techniques such as chromatography or spectroscopy.

WebIn concentrating solar systems, it is essential to study the optical losses of the collectors. A fundamental parameter is the intercept factor, namely, the fraction of sunrays reflected by the concentrator that reaches the receiver.
