Determination of styrene content in Gorgonzola PDO cheese by headspace solid phase micro-extraction (HS-SPME) and gas-chromatography mass-spectrometry (GC-MS)

Control of the composition of products that are intended for use as packaging material is essential, particularly when these products come into direct contact with food.

Microfabrication of high temperature micro-reactors for continuous flow isotope ratio mass spectrometry

These micro-reactors could also be manufactured at larger channel dimensions to enable robust operations for normal GCC-IRMS applications. Photolithography was used to define the reactor channel pattern on high purity fused silica, with a protective layer of amorphous silicon.

Challenges in the indirect quantitation of acyl-glucuronide metabolites of a cardiovascular drug from complex biological mixtures in the absence of reference standards

This paper describes the quantitation of acyl-glucuronide metabolites (M26 and M5) of a cardiovascular-drug (torcetrapib) from monkey urine, in the absence of their reference standards.

Reaktionen des metalloiden Clusteranions {Ge9[Si(SiMe3)3]3}- in der Gasphase. Oxidations- und Reduktionsschritte geben Einblicke in den Bereich zwischen metalloiden Clustern und Zintl-Ionen

Unlike former results with off-resonant excitation the fragmentation leads mainly to the end-product Ge9-. Moreover, applying an on-resonant excitation the dissociation experiment can be quantified; 2.0 ? 0.15 eV (193 ? 15 kJ?mol-1) for the elimination of the first two ligands and 2.7 ? 0.

Formation and Stability of Gaseous WS2Cl2, WS2Br2 and WS2I2 - A Combined Experimental and Theoretical Study Dedicated to Professor Rüdiger Kniep on the Occasion of His 65th Birthday

Gaseous WS2Cl2 and WS2Br2 are formed by the reaction of solid WS2 with chlorine resp. bromine at temperatures of about 1000 K. This could be shown by mass spectrometric measurements.
