The document emphasizes that users must have practical experience in formal laboratory work when measuring arsenic content in inorganic chemical products. At the same time, it warns that this document does not cover all possible safety issues. Users are responsible for taking appropriate safety and health measures and ensuring compliance with relevant national regulations. The document describes the test method for the determination of arsenic content in inorganic chemical products using Atomic fluorescence spectrometry, AFS. Applicable to the determination of arsenic content in inorganic chemical products. Relevant standards are cited in the document, such as specifications and test methods for analytical laboratory water (GB/T 6682-2008), Atomic Fluorescence Spectrometer (AFS) (GB/T 21191), and the preparation of standard solutions, preparations and products for chemical analysis of inorganic chemical products. The reagents and water used in the document usually refer to the analytical pure reagents and the specified secondary water. The principle section describes in detail the Sample Handling, the arsenic reduction process, and the steps for the determination of arsenic content by Atomic fluorescence. The document also specifies the preparation requirements for the reagents, impurity standard solutions, preparations, and products used in the test.
