This standard specifies a method for the determination of calcium content in lithium fluoride by flame atomic absorption spectroscopy (AAS), applicable to the determination of calcium content not exceeding 0.50%. After the sample is fluorinated with perchloric acid, the calcium content is determined at a wavelength of 422.7 nm by AtomicAbsorption Spectroscopy under air-acetylene flame conditions. The standard details the reagents, instruments and experimental procedures to ensure the accuracy and repeatability of the experimental results.
