## GeoImage™ for Petrography

Measure the reflectance of vitrinite macerals

GeoImage™ uses a camera to quickly and accurately measure the reflectance of vitrinite macerals. GeoImage™ is designed for the organic petrographic analysis using Standard Test Methodologies ISO 7404-5 and ASTM D2798.

GeoImage™ works by reading the vitrinite reflectance intensity from each pixel of a calibrated camera. This means that, in the standard configuration, millions of points can be measured at one time…making vitrinite reflectance testing quick, easy and accurate.

Perfect Vision for Science™

ISO 7404 and ASTM D2798

The GeoImage™ is designed to measure the reflectance of vitrinite macerals per ISO 7404 and ASTM D2798 standard methods. Offered both in manual and automated mode, the system produces industry standard reports when used with [CRAIC Vitrinite Reflectance Standards](https://www.microspectra.com/technical-support/96-vitrinite-reflectance-standards/). Test reports can also be customized to your particular requirements.

## Point Counting

Point counting is a statistical method wherein the petrographer analyzes a large number of points, typically 100 to 500, and recording the type of rock seen at each point. The entire dataset is then analyzed to give a more detailed description of the rock sample.

## Imaging

High resolution color digital imaging

The GeoImage™ offers high resolution, color digital imaging with sophisticated software. This makes it very easy to align the sample for measurements and to capture full color images under any measurement conditions.

## Fluorescence

Cutting edge microfluorometry

The GeoImage™ can also image the fluorescence of coals, kerogens and petroleum source rock easily and quickly. With the ability to image, the GeoImage™ is a powerful tool for the analysis of geological samples…including fluid inclusions.

## Applications

- Vitrinite Coal Reflectometry
- Organic Petrography
- Kerogen Analysis
- Petroleum Source Rock Analysis
- Petrochemistry
- Color imaging
- Mineralogy analysis
