Particulate contamination analysis using microscopy and spectroscopy methods can identify and mitigate contamination in chemical, consumer products, industry or processes. Particulate analysis is the first stage in resolving contamination issues that could be potentially critical. These issues can take place at many points through the supply chain of numerous industries. Particulate contamination identification means that action can be taken to mitigate and prevent further or additional contamination.<\/p>\n\n\n\n

How does Particulate Contamination Work?<\/h2>\n\n\n\n

Particulate contamination investigations involve identifying microscopic particles, the isolation of various particulate phases of in-homogenous production deposits and determining the source of the contaminants.<\/p>\n\n\n\n

Mitigating particulate contamination can be done by identifying contaminants through expertise in sampling and sample preparation, chemical identification, physical\/visual examination and root cause analysis.<\/p>\n\n\n\n

Contaminant particles can be digitally imaged using microscopy to offer forensic traceability. Once the initial microscopical assessment has been carried out, analysis can be undertaken using energy-dispersive X-ray spectroscopy on isolated particles with scanning electron microscopy (SEM) or vibrational spectroscopy. Characterization of the shape or size of particulate contamination can be carried out using photomicrography.<\/p>\n\n\n\n
