HJ 509-2009 Translated English of Chinese Standard. HJ509-2009: Determination of Platinum, Palladium and Rhodium loading in the vehicle-used ceramic catalytic converters - Inductive coupled plasma-optical emission spectrometry and inductive coupled plasma-mass spectrometryhttps://www.chinesestandard.net, 13 mars 2014 - 19 pages This Standard specifies inductive coupled plasma-optical emission spectrometry (ICP-OES) and inductive coupled plasma-mass spectrometry (ICP-MS) for the determination of platinum (Pt), palladium (Pd) and rhodium (Rh) loading in the vehicle-used ceramic catalytic converters. This Standard is applicable to the determination of Pt, Pd and Rh loading in catalytic converters with cordierite honeycomb ceramics as the carrier and precious metal as the active constituent. |
