Vitrinite Reflectance Standards

Vitrinite Reflectance Standards for use with the CoalPro II™ Vitrinite Reflectance Measurement System.

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

When used with the CRAIC Microspectra Vitrinite Reflectance Analysis™ software, CRAIC Vitrinite Reflectance Standards are part of an automated 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.
