Certification of the mass fractions of trace elements and pentachlorophenol in an impregnated wood reference material

Autor: Hans-Gerhard Buge, Roland Becker, Detlef Lück, Wolfram Bremser, Holger Scharf

Publikováno v: Accreditation and Quality Assurance. 15:613-619

The resource-saving utilisation of recovered waste wood is a matter of growing concern. In several European countries, this utilisation is governed by regulations and is dependent on the contents of certain trace elements and organic compounds. Thus,

Purity of potassium hydrogen phthalate, determination with precision coulometric and volumetric titration–A comparison

Autor: Joachim Pautz, Martin Breitenbach, Sebastian Recknagel, Detlef Lück

Publikováno v: Analytica Chimica Acta. 599:256-263

The mass fraction of potassium hydrogen phthalate (KHP) from a specific batch was certified as an acidimetric standard. Two different analytical methods on a metrological level were used to carry out certification analysis: precision constant current

Certification of the extractable contents of Cd, Cr, Cu, Ni, Pb and Zn in a freshwater sediment following a collaboratively tested and optimised three-step sequential extraction procedure

Autor: Detlef Lück, Ph. Quevauviller, José Fermín López-Sánchez, Herbert Muntau, M. Pueyo, Gemma Rauret, M. Yli-Halla

Publikováno v: Journal of Environmental Monitoring. 3:243-250

Sequential extraction procedures have been used during the last decades to study and determine trace element mobility in aquatic sediments. However, the results obtained are operationally defined and, therefore, the significance of the analytical res

Validation of a European standard for the determination of hexavalent chromium in solid material

Autor: Holger Scharf, Domenico Calzolari, Monika Kisser, Rob Cleven, Kristof Tirez, Detlef Lück

Publikováno v: Journal of environmental monitoring : JEM. 9(7)

A European standard for the determination of Cr(VI) in solid material has been elaborated in the framework of an international co-operation and finally validated in the course of an interlaboratory comparison. The procedure is based on the alkaline d

A novel solid phase extraction method for pre-concentration of gadolinium and gadolinium based MRI contrast agents from the environment

Autor: Norbert Jakubowski, Ulrich Panne, Chinthalapati Siva Kesava Raju, Holger Scharf, Detlef Lück

Publikováno v: Journal of Analytical Atomic Spectrometry. 25:1573

An efficient solid phase extraction (SPE) method using bis-(2-ethylhexyl)-phosphate (HDEHP) coated reverse phase C18 support has been developed for the pre-concentration of Gadolinium (Gd) and Gd contrast agents widely used in magnetic resonance imag
