Unique offline position

Mounted on a rail, a CNA³ can be easily moved to the side for maintenance, cleaning, neutron generator swap, etc. This position, also called offline position, gives our customer the unique opportunity to perform a sample measurement in order to check performances of the system and apply correction if necessary, without the need to stop production. 




Coal is an important industrial mineral both as a fuel and feedstock. Coal quality can vary greatly depending on the source, hence the usage and price are highly dependent on the composition.
Whether located directly at a mine, a coal processing plant, a metallurgical plant, a power plant or other usage point, the CNA³ can provide reliable real-time information on the coal composition, calorific value, ash content, volatile matter, and moisture. The CNA³ neutron generator technology enables measurement of a wide range of elements, including C and O.


The CNA³ design is particularly suited for conveyor belts carrying copper ore. The unit is designed to accommodate wide belts with variable loading and a wide range of particle sizes. With the entire unit below the belt, oversize material passes harmlessly over the analyzer. The unit provides elemental data for a wide range of elements. This data can be used to guide mining operations, sort material streams, and provide feed forward process control information.


With its large calibration range, the CNA³ can analyze a wide range of iron ore. The unit can be located deep underground or at ground level and can provide elemental information to guide mining operations and/or mix different ores to a target composition to reduce variability in downstream processes.


Whether used at the mine or in downstream processing, the CNA³ can provide information to control nickel grade, Fe/Ni ratio, basicity index and other key process parameters. Powered by a neutron tube, the CNA³ provides a controlled neutron flux for stable operation and unmatched safety.
