LOR stands for “Limit of Reporting,” which refers to the lowest concentration of a substance that a laboratory can reliably detect and report in a sample.
BSiO2 Pty Ltd samples were tested with a result of less than 1% of crystaline silica.
In the context of diatomaceous earth analysis, LOR <0.01 for quartz and cristobalite indicates that the laboratory’s method can accurately detect and report concentrations of quartz and cristobalite that are below 0.01, likely in terms of milligrams per cubic meter (mg/m³).
This information is important for understanding the sensitivity of the analysis method and ensuring that the results are accurate and reliable.
In Australia, laboratories may choose to report their LOR for quartz and cristobalite in diatomaceous earth samples because these substances are relevant for occupational health and safety considerations. Quartz and cristobalite are two common forms of crystalline silica, which can pose a health risk if inhaled in significant quantities over time.
