Development of the new test method, ASTM D7708-11, began in 2008 with a survey of common practices used in laboratories that routinely measure the reflectance of dispersed vitrinite in shales.

Through the use of a connected camera, GeoImage™ is capable of quickly and accurately measuring the reflectance of vitrinite macerals. As a tool that has been specifically designed for organic ...

Optical properties measurement on most coatings, materials and surfaces, from roofing to satellites. Solar reflectance; thermal emittance, SRI,all those needed for LEED certification. Optical ...

Measures total hemispherical reflectance, 3 to >35 micrometers, and performs integrated total hemispheric reflectance measurement, 250 nm to 2500 nm. The TESA 2000, by virtue of an advanced optical ...

One of the most popular techniques for material identification is single bounce ATR spectroscopy. However, in some cases, the specular reflectance sampling technique may still be necessary. Much like ...

Vitrinite reflectance was measured on coal samples from eight Pennsylvanian stratigraphic units from the Bluejacket Coal (Cherokee Group, Desmoinesian) to a coal in the West Branch Shale (Admire Group ...
