Chemical Assays

Fast Assay Turnaround

Scanning with XRF is fast, the Minalyzer CS can analyse between 12 and 20 meters of core per hour depending on the quality of the core and the type of core tray. Processing of the spectral data is done locally as the scanning is progressing providing immediate assays on-site. Reduce risky and expensive logistics of valuable samples.

Continuous and Representative

The XRF spectral data is acquired through a continuous movement along the complete length of the core sample. The XRF footprint is a line of 20 x 1 mm creating an area on the sample which makes the analysis less subjective, repeatable and highly representative.

The area in blue represents the area scanned by the X-ray beam. The graphs below show an example of comparisons between Minalyzer CS XRF and corresponding laboratory bulk XRF assay on the same intervals.


The elemental range spans from elements Mg to U, providing whole rock analyses for your complete project. Find correlations between elements that you previously have not included in your analytical suite for the full lenght of your core. The detection limits can be optimized through a range of parameters such as scanning speed and interval length. Contact Minalyze for up to date detection limits for the elements of interest in your project.

High Resolution

The spectral data is stored in cm intervals and can be integrated and processed on any interval from cm to several meters. This is useful for identifying contacts, distinguishing veins and helps classify different rock types when logging. It makes the logging more objective and reduce logging time as well as the amount of re-logging. This data set also makes the sample selection more objective and the risk of sampling across contacts are reduced, furthermore it could possibly reduce the need for traditional destructive sampling.

Scanning samples is completely non-destructive and minimal sample preparation is required. The sample surface should be visually clean from dust, mud and other contaminants. Keeping your samples intact enables for subsequent mechanical testing and saves time on time consuming tasks of sample preparation such as splitting, cutting, crushing and grinding samples.

Compatible Data Set

The quantified assay data is available as a comma separated table format which enables for easy import in your database or modelling software such as Leapfrog®, directly after scanning. It is possible to align the data taking distance markers and core loss into account.
