CRAIC Technologies launch GeoImage™ for petrographic analysis

GeoImage™ is the latest Vitrinite Reflectance Measurement System from CRAIC Technologies and is used to determine the grade of coal and coke by vitrinite reflectance as per the ISO 7404-5 and ASTM D2798 standards. These procedures ensure that coal blends used in energy generation and steel making are optimal and consistent from batch to batch.

Designed for use with petrographic microscopes, GeoImage™ can also be used in conjunction with CRAIC’s microspectrometers to also acquire reflectance and fluorescence spectra of coal samples, and take high resolution colour images too.

GeoImage™ also features an automated point counting module where hundreds of points are measured on the sample. Using statistical data analysis, the amount of vitrinite* in the coal blend, its thermal maturity and thus its energy content can be quickly determined.

For more information about GeoImage™ and other products from CRAIC Technologies, please contact us.

* Vitrinite is a maceral of coal and is comprised of various polymers, cellulose and lignin. Measuring the amount of light reflected by vitrinite macerals is a key test to determine the thermal maturity of the coal blend and its suitability for steel production. The procedure has been standardised by a number of international bodies including both ISO and ASTM.

CRAIC’s Technologies MP-2™ Photometer can upgrade your microscope

The CRAIC Technologies MP-2™ Microscope Photometer is designed to add photometry and imaging to an optical microscope. With a spectral range from the deep UV to the near infrared, the MP-2™ is better described as a microscope radiometer. It is limited only by the microscope’s optics.

The CRAIC MP-2™ microphotometer enables collection of transmission, reflectance or even fluorescence and luminescence photometric data of microscopic samples.

mp-1The MP-2’s solid state detectors have dynamic ranges and sensitivities greater than PMTs or imaging systems and with complete software control, either broad- or narrow-band, photometric intensity measurements can be made. Typical applications include:

  • Cytophotometry & immunohistochemistry
  • Cytofluorimetry & immunofluorescence
  • Intracellular calcium measurements
  • Gemology & mineralogy
  • Thickness measurements
  • Ion & pH measurements
  • DNA analysis
  • Photoreceptor analysis

Gamma Scientific hones GS-1290 wavelength accuracy to ±0.2 nm

Gamma Scientific‘s RadOMA™ range of advanced, high-speed spectroradiometers deliver millisecond measurement speeds, exceptional low-light measurement capabilities, and superior blue-light region sensitivity. The latest versions of the GS-1290 are now offering wavelength accuracies down to ±0.2 nm.

Multiple configurations cover a wide spectral range, from the ultraviolet to the near infrared:

1220 Display Measurement System

  • 200 to 890 nm (GS-1290-1)
  • 200 to 1100 nm (GS-1290-2)
  • 360 to 940 nm (GS-1290-3)

RadOMA™ spectroradiometers are ideally suited for testing retroreflected colour, reflectance and transmittance, LED colour and luminance, flat panel displays, and light sources.

The systems are completely modular and interchangeable for easy upgrade or customisation, and can be self-calibrated by the user so they never have to be returned to the factory.
