Beta Analytic utilizes chemical methods as outlined in ASTM D6866. The standard is available for download (for a fee) from ASTM.
Quality control measures at Beta are designed to ensure the accurate reporting of every result. Internal standards are run daily. Multiple cross-checks (including bar-coding) are performed throughout each analysis. Internal and external controls are analyzed routinely to measure and monitor ongoing laboratory accuracy and reproducibility.
Calculation and reporting of results are performed using in-house software with built-in multiple cross-checks for each result. Citing the full list of cross-checks is beyond the scope of this document. A broad system of cross-checks comprises 300 pages of quality control commitment outlined in Beta’s ISO-17025 quality assurance documentation.
Beta's quality assurance program is audited annually by the Department of Energy for work done in previous years for the nuclear storage industry.
