DustScanAQ offer a range of other analytical techniques, through accredited partner laboratories, to complement our optical microscopy, elemental and chemical analyses. X-Ray Diffraction (XRD) can be used to identify the minerals present within the crystalline fraction of dust samples by determining their unique atomic and molecular structure. This analytical technique is typically employed when quantitative data are required from samples that are predominantly crystalline in nature.
When assessing workplace exposure to dust, there may be a need to test for Respirable Crystalline Silica (RCS). RCS is a known carcinogen and can be generated through processes such as cutting stone or handling certain aggregate materials. RCS can be of particular concern at sites involved with construction, demolition, mineral extraction or aggregate recycling. DustScanAQ utilises the XRD services at the Health and Safety Laboratory (HSL) and others to assess workplace exposure to RCS. The results are included as part of the workplace exposure report.
Other tests on dust include particle size analysis (PSA) and density measurement. PSA produces a particle grading curve showing the size distribution of particles. Particle size analysis can be used in environmental forensics studies where materials of interest have a known size fraction.
DustScanAQ has links with numerous academic institutions, including the Universities of Portsmouth, Oxford, Newcastle upon Tyne and Leeds. This enables us to design detailed plans of analysis to suit the specific needs of our clients.
