GB/T 7717.16-2022 《Acrylonitrile for industrial use—Part 16: Determination of iron and copper content—Graphite furnace atomic absorption spectrometry and inductively coupled plasma mass spectrometry》 Related products

This standard specifies two methods for the determination of iron and copper content in industrial acrylonitrile: Graphite furnace atomic absorption-tion spectrometry, GFAAS and inductively coupled plasma Mass spectrometry. Graphite furnace atomic absorption-tion spectrometry, GFAAS is suitable for the determination of iron and copper content in the range of 0.010 mg/kg to 1.000 mg/kg, while inductively coupled plasma Mass spectrometry is suitable for the determination of iron and copper content in the range of 0.005 mg/kg to 1.000 mg/kg. The standard provides specific operating procedures and testing requirements to ensure the accuracy and repeability of test results.
