Wenn Nanogramm das Aroma verändern

Abstract

Ein robuster Baustein für magnetische Systeme resultierte aus einer neuen, effizienten Synthese des [ReF6]2−‐Ions. K. S. Pedersen, R. Clérac, J. Bendix und Mitarbeiter berichten in ihrer Zuschrift auf dass nach Einbau des [ReF6]2− in ein NiII‐ReIV‐1D‐Koordinationspolymer das Fluorid signifikante magnetische Kopplungen vermittelt. Die ferromagnetische Ni‐F‐Re‐Wechselwirkung (+11 cm−1) stellt die in verwandten Cyanid‐verbrückten Systemen beobachteten Werte in den Schatten.

Current Developments in Analyzing Food Volatiles by Multidimensional Gas Chromatographic Techniques

“…On the other hand, Select-eV already can be used in a fast-switching ionization mode, named tandem ionization, which affords two sets of MS data to be acquired and further processed. Applications for Select-eV have been described in the petrochemical field and also in aroma analysis . An example of mass spectral signatures with enhanced molecular ions for ethylphenols in wine is provided as Supporting Information in Figure SF1.…”

High-resolution MS (HR-MS) represents an ultimate option for selective detection leading to unambiguous structure elucidation or confirmation.…”
