GB/T 6324.11-2021 Test method of organic chemical products—Part 11:Determination of trace arsenic in liquid products—Atomic fluorescence spectrometric method (English Version)
This document specifies a method for the determination of trace arsenic in liquid chemical products using atomic fluorescence spectrometry. This document is applicable to the determination of trace arsenic in organic liquid chemical products such as hydrocarbons, alcohols and acids. When the sample weight is 1.0 g and the constant volume is 50 mL, the detection limit of the method in this document is 0.01 mg/kg.
