Warsash Scientific offers a new vitrinite reflectance measurement system recently introduced by CRAIC Technologies.
The 308 Coal is used to measure vitrinite reflectance and fluorescence to quickly determine the thermal maturity of coal and coke.
Vitrinite is a maceral of coal and is comprised of various polymers, cellulose and lignin. Measuring the amount of light reflected by vitrinite macerals assists in determining the thermal maturity of the coal blend and its suitability for steel production.
Designed to determine the grade of coal and coke, the vitrinite reflectance method ensures that the coal blends used in energy generation are optimum and consistent. The 308 Coal can also be used to acquire fluorescence and reflectance spectra of geological samples in order to more accurately grade them.
Standardised by a number of international bodies including both ISO and ASTM, all the standards require the use of microscope spectrophotometers such as the 308 Coal that can measure the intensity of light reflected from a microscopic sampling area.
Key features of the 308 Coal vitrinite reflectance measurement systems:
- Measures the reflectance and fluorescence spectra of coals in addition to capturing digital images in full colour
- Measures the amount of light reflected from samples of the coal blend at hundreds of points for statistical analysis by a computer
- Statistical analysis determines the coal sample’s vitrinite content, thermal maturity and value for coking
- Eliminates conventional time-consuming process through automation while improving the lab’s throughput and accuracy
- Results provided as a histogram help determine the thermal maturity of the coal to be used in steel production
