Solid mineral fuels. Determination of arsenic and selenium. Eschka’s mixture and hydride generation method algolia-search-ignore these listed minimums are designed1 Scope This document specifies a method using Eschka's mixture during ashing, extraction of the ash residue with acid, and hydride generation atomic absorption spectrometry or hydride generation atomic fluorescence spectrometry, for the determination of arsenic and selenium in solid mineral fuels. NOTE The method is also applicable to the determination of the analytes by hydride generation inductively coupled plasma atomic emission spectrometry.
