A new certified reference material for the quality control of palladium, platinum and rhodium in road dust, BCR-723

A method for determination of PGE–Re concentrations and Os isotopic compositions in environmental materials

“…42 This catalyst-associated PGE certied reference material is widely used in analytical laboratories examining various environmental materials (road dust, soil, sediment, and airborne particulate matter). The PGE-Re concentration and 187 Os/…”

A re-examination of platinum-group element concentrations in the environmental certified reference material BCR-723

“…It is officially known as BCR-723 and is available from the Institute for Reference Materials and Measurements (IRMM), Geel, Beligum [20,21]. The certified means (AESD) are: Pt, 81.3 AE 4.6 ng g À1 ; Pd, 6.0 AE 2.2 ng g À1 ; and Rh 12.8 AE 1.6 ng g À1 [21].…”

“…Since the introduction of BCR-723 (CW-8), the only statistical exploration of the concentration data submitted for PGE certification was provided by the original studies of Zischka et al [20,21]. The objectives of this study are to present a new quantitative exploration of the original PGE data with robust procedures, examine particular claims made in the original certification documents, and compare PGEs in BCR-723 with those representative of various European environmental media.…”

“…The objectives of this study are to present a new quantitative exploration of the original PGE data with robust procedures, examine particular claims made in the original certification documents, and compare PGEs in BCR-723 with those representative of various European environmental media. During the original certification process, participating laboratories performed a minimum of six independent replicate measurements of each element on at least two different bottles of BCR-723 on at least two different days [21]. The six averaged replicates from each accepted data set were tabulated in Zischka et al [20], and an overall mean was computed for each.…”

Improved separation of palladium species in biological matrices by using a combination of gel permeation chromatography and isotachophoresis

“…One reason for this is the lack of analytical methods for Pd in the trace and ultratrace range, and the presence of severe mass interferences in inductively coupled plasma (ICP-MS) [15]. Recently, an effective separation and preconcentration method for Pd and Au was developed [16] and validated [17,18]. After sample decomposition both elements are collected by reductive coprecipitation with mercury.…”
