About This Item
ASTM D4382 is the ASTM standard for determining barium in water using atomic absorption spectrophotometry with a graphite furnace. It is intended to support consistent laboratory measurement of barium at low concentrations, where reliable detection and repeatable results matter. As a technical document, it helps laboratories and buyers align on a common test approach for water analysis, supporting quality control, compliance work, and product evaluation under a recognized ASTM method.
What is ASTM D4382?
This standard defines a test method for measuring barium in water by atomic absorption spectrophotometry using a graphite furnace. In practical terms, ASTM D4382 provides a structured laboratory procedure for analyzing water samples with an instrument-based technique designed for trace-level measurement. The standard is most useful when users need a recognized method reference for producing consistent analytical results and comparing data across laboratories, instruments, or routine water testing programs.
Where is ASTM D4382 used?
ASTM D4382 is commonly used in water testing laboratories and other analytical settings where barium measurement is needed. It is relevant for testing water samples as part of environmental monitoring, laboratory quality control, and analytical reporting. The graphite furnace atomic absorption approach is especially suited to workflows that require sensitive instrumental analysis, making this standard useful wherever water composition must be checked with a defined and repeatable ASTM method.
Why is ASTM D4382 important?
This standard matters because it supports consistent barium testing in water using a recognized laboratory method. ASTM D4382 helps reduce variation in how results are generated and reported, which is important for compliance activities, procurement decisions, and technical review. For organizations that rely on water analysis, using a standard method can improve confidence in data quality, simplify comparison between test results, and strengthen overall quality control practices.
