Case Study: Coarse CRM Analysis Identifies Crusher Malfunction
A major iron ore mining company in the Pilbara operates an automated laboratory for routine analysis of production samples. Coarse Certified Reference Materials (CRM) were used to monitor the performance throughout the analytical process from sample preparation, to bead fusion and analysis.
Timely quality control (QC) data of the coarse CRM allowed for the identification of automated sample crusher failure within the sample preparation stage, resulting in an analytical bias. Prompt action also prevented compromising further production samples.
