About This Item
ASTM D3986 is the ASTM standard for measuring barium in brines, seawater, and brackish water by direct-current argon plasma atomic emission spectroscopy. It provides a clear technical basis for evaluating barium in high-salinity water samples where accurate trace analysis may be important. This standard is commonly used to support laboratory testing, quality control, and data consistency when comparing results across water chemistry applications.
ASTM D3986 standard overview
The Standard Test Method for Barium in Brines, Seawater, and Brackish Water by Direct-Current Argon Plasma Atomic Emission Spectroscopy defines an analytical approach for determining barium in saline water matrices. Its purpose is to give laboratories a recognized method for instrumental measurement using direct-current argon plasma atomic emission spectroscopy. As an ASTM standard, it helps align testing practices around a specific measurement technique and sample type, supporting more consistent reporting and evaluation of water chemistry data.
Where is ASTM D3986 used?
This standard is typically used in laboratory settings that analyze saline water samples, including brines, seawater, and brackish water. It may be applied in routine environmental or industrial water testing workflows where barium measurement is needed for characterization, monitoring, or comparison purposes. ASTM D3986 is also relevant wherever direct-current argon plasma atomic emission spectroscopy is used to generate dependable elemental analysis results for these water matrices.
Practical importance of ASTM D3986
ASTM D3986 matters because it supports consistent barium testing in water samples that can be challenging because of their salt content. Using a recognized ASTM method can help improve comparability between laboratories, strengthen quality control, and support procurement or compliance-related decisions that depend on reliable analytical results. It also gives technical teams a clear reference for evaluating barium measurements in saline water systems with greater confidence.
