Used as a reference solution in laboratories to calibrate instruments for the accurate determination of molybdenum levels in water samples. Ensures precision in environmental monitoring, especially in testing drinking water, wastewater, and industrial effluents for trace metal contamination. Helps maintain compliance with regulatory standards by providing consistent and reliable analytical results. Commonly used in techniques such as atomic absorption spectroscopy (AAS), inductively coupled plasma mass spectrometry (ICP-MS), and spectrophotometry.
