GMS312 Rolling Core Spectral Analyzer
Description

The GMS312 Core Analyser is a Rolling Gamma Spectrometer designed to detect naturally occurring gamma radiation. Cores from 3.5 in. to 12 in. can be accommodated.

“…on site core analysis allows the operator to make effective, real-time assessments of the well site.”

The GMS 312 offers the ability to log elemental concentrations of Uranium, Thorium, and Potassium by means of spectral analysis of gamma emissions from core materials. Data can be displayed in either API units or counts in six user-defined Regions of Interest plus gross gamma count.

There are two measurement modes; Dynamic and Static. In the Dynamic mode, continuous measurements are made whilst the GMS312 is rolled along the core at a preset speed. In the Static mode, the GMS312 is moved to each location and a static measurement is made. In each mode, the depth is displayed.

Survey results are saved to the internal memory of the instrument so that they may be downloaded and analyzed on a PC via the Core Analyzer Application software.
