Report of the CCQM-K124: trace elements and chromium speciation in drinking water—part A: trace elements in drinking water, part B: chromium speciation in drinking water

Abstract: CCQM-K124 was organized by the Inorganic Analysis Working Group (IAWG) of CCQM to assess and document the capabilities of the national metrology institutes (NMIs) or the designated institutes (DIs) to measure the mass fractions of trace elements (As, B, Cd, Ca, Cr, Hg and Mo) and hexavalent chromium (Cr(VI)) in drinking water. The National Metrology Institute of Japan (NMIJ) and the Government Laboratory, Hong Kong SAR (GLHK) acted as the coordinating laboratories. This comparison is divided int… Show more

“…The Inorganic Analysis Working Group of the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology (CCQM) lists the consideration of the IIF phenomenon as one of the core capabilities in ID-ICP-MS measurements [11,15]. Only a few participating laboratories state that this is not necessary in double ID-ICP-MS [11,15].…”

“…IIF cancellation. It should be noted that IIF is often referred to as mass discrimination, mass fractionation, or mass bias in the literature [11,15,16]. However, these expressions can be misleading because it is isotope ratios, rather than masses, that are biased.…”
