Simultaneous determination of sulfamethoxazole and trimethoprim in bovine milk
The development and validation of a multidimensional HPLC method using an on-line clean-up column coupled with amperometric detection employing a boron-doped diamond (BDD) electrode for the simultaneous determination of sulfamethoxazole (SMX) and trimethoprim (TMP) in bovine milk are presented in Analytica Chimica Acta [654 (2) 127–132 (2009)].
Identification and Characterization of Polyphenolic Antioxidants
Dr Per Sjöberg from the Department of Physical and Analytical Chemistry at Uppsala University in Sweden has demonstrated that electrochemistry (EC) coupled to liquid chromatography (LC) and electrospray ionization tandem mass spectrometry (LC/EC/ESI-MS/MS) can be used to rapidly obtain information about the antioxidant activity
Influence of Storage Conditions on Aroma Compounds in Coffee Pads by Using Static Headspace GC-MS
Dr Bart van der Bruggen and a team from the Department of Chemical Engineering, KU Leuven and PerkinElmer, Belgium, employed static headspace gas chromatography coupled to mass spectrometry (SHGC–MS) to identify aroma compounds in coffee pad powder.
Understanding protein phosphorylation with nano-ultra performance liquid chromatography-tandem mass spectrometry
Professor Wolf Lehmann, from Molecular Structure Analysis at the German Cancer Research Center (DKFZ) Heidelberg, Germany, conducted a study to characterize in detail the in vitro phosphorylation of the recombinant Plasmodium falciparum protein GAP45 by a kinase from the same organism.
Detection of human bladder cancer in human by LC-MS analysis of urine
The current use of cystoscopy for screening and detecting bladder cancer is invasive and expansive. Various urine-based biomarkers have been used for this purpose with limited success.
