Lucideon Helps Regain Services Improve Analyses’ Robustness

Regain Services PTY Ltd purifies aluminium smelting waste material for re-use as a raw material.  They provide a technology that eliminates the key hazards in the by-product material.  The result is high quality products that deliver energy saving and CO2 reduction benefits for cement and clay brick manufacturers.

The Challenge

Due to the complex nature of the smelter mixtures, key material attributes such as particle size, counting statistics and particle orientation were affecting XRD (X-Ray Diffraction) quantification of the sample, with different labs and techniques producing varying results.
Regain Services PTY Ltd wanted to develop an accurate and consistent method of determining and quantifying the constituents of a complex reprocessed industrial solids mixture and asked Lucideon to develop a protocol.

What We Delivered

At Lucideon we used our expertise in XRD and complimentary analytical techniques; XRF (X-Ray Florescence), ICP (Inductively Coupled Plasma), FTIR (Fourier Transform Infra-Red) and SEM (Scanning Electron Microscope) to develop the protocol for Regain to use, one that would allow more consistent quantification.  Relying solely on XRD and perhaps XRF can make peak assignment difficult.  We knew that combining these analytical techniques and using them in conjunction with robust procedures would allow complete characterization of complex solid mixtures.

Thus, a protocol to minimise the discrepancy between the two techniques was developed and its robustness was tested on mixtures of over 20 phases with excellent results.

Value to the Client

The new test for the quantification of complex industrial solid mixtures acted as a robust tool that Regain Services could confidently use to inform their decisions, such as optimising materials cleaning regimes, checking for batch to batch consistency and understanding how materials vary with smelting location.  By sharing the new test procedure with clients, Regain is helping to raise confidence in the quality of their raw materials along supply chains for existing and potential end applications.
