GB/T 23950-2009 《Inorganic chemicals for industrial use - General method for determination of heavy metals》 Related products
This standard specifies the visual colorimetry method for the determination of heavy metals (in terms of lead) content in inorganic chemical products. It is suitable for the detection of heavy metals limits, ranging from 0.2 µg/mL to 2 µg/mL. The standard describes in detail safety tips, reagent requirements, instrumentation, analysis procedures, etc., and provides a unified technical specification for the detection of heavy metals content in inorganic chemical products to ensure product mass and safety.
