Eine praxisorientierte Bestimmung der Nachweisgrenze

Zusammenfassung Am Beispiel der Spurenanalyse von Quecksilber in biologischem Material wird eine Methode zur Bestimmung der Nachweisgrenze vorgeschlagen, die die Nachweisgrenze als geringsten, mit einer bestimmten Präzision meßbaren Gehalt auffaßt und unter Anwendung einfacher statistischer Kalküleals solche ermittelt.

A practice-orientated determination of the limit of detection

Summary Illustrated by mercury trace analysis in biological material, a method for determining the limit of detection is proposed. It interpretes limit of detection as lowest content measurable with a certain precision and ascertains itas such applying simple statistical calculus.

     

An enhanced model for probabilistic cleavage fracture assessment considering local constraint effects

The present study is concerned with the development of an enhanced probabilistic model for cleavage assessment of ferritic steels. An enhanced model for the probabilistic cleavage fracture assessment has to consider the conditions for both, nucleation and propagation of micro defects. Hence, a propagation based model is enhanced by a combination of the local plastic strain and the local stress triaxiality to account for the nucleation of potentially critical micro defects. The formulation of the new model is based on the local mechanical field quantities determined numerically at the cleavage origins for a variety of standard deep and shallow crack specimens as well as for small scale cruciform bending specimens.

Liquid chromatography-mass spectrometry in metabolic research. I. Metabolites of benzbromarone in human plasma and urine.

Seven benzbromarone metabolites were identified in human plasma and urine by electron-impact mass spectrometry after semipreparative high-performance liquid chromatographic fractionation and/or by liquid chromatography-mass spectrometry using a thermospray interface. The major metabolite in plasma and urine was a hydroxybenzofuranoyl species; the 1-hydroxyethyl entity was identified as a minor metabolite. Five urinary metabolites occurred in trace amounts, all of them carrying OH and/or C = O groups in different positions. The hydroxybenzofuranoyl metabolite has often been mistaken for benzarone in previous studies.
