HG/T 2415-2007 (English Version) PDF

Scope: This standard specifies the method for the determination of trace metals such as copper, iron, zinc, nickel, lead, chromium and other trace metals in couplers by flame (acetylene-air) atomic absorption spectrometry. This standard is applicable to the determination of trace metals such as copper, iron, zinc, nickel, lead, chromium and other trace metals in couplers whose ignition residues can be dissolved in hydrochloric acid or nitric acid. The detection limits are 0.03μg/mL, 0.20μg/mL, and 0.02μg. /mL, 0.20μg/mL, 0.10μg/mL, 0.02μg/mL.
