Vitrinite Reflectance Standards

Vitrinite Reflectance Standards for use with the CRAIC Technologies vitrinite reflectance measurement systems.

CRAIC Technologies™ offers a variety of mono-crystalline prisms designed for calibration of vitrinite reflectance measurement microscope photometers, such as the GeoImage™ imaging photometer, at 546 nm. The materials of each prism varies so that the GeoImage™ system can be calibrated across a range.

When used with the CRAIC coal analysis software, CRAIC Vitrinite Reflectance Standards are part of an calibration procedure. They are simple to use and result in high quality vitrinite reflectance measurements that comply with ISO, ASTM and other international testing protocols for vitrinite coals.
