Synthesis of 13C-labeled drugs of abuse as internal standards for reducing differences in ion suppressing/alteration effects in LC/MS-MS quantification
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:351, Doctoral thesis, 2014)
Stable isotope labelled internal standards (SIL ISs) are often used when legal and illegal drugs are analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Ideally an IS behaves identically as its corresponding ...
EBSD based in-situ observationsof polycrystalline materials in the SEM
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:81, Doctoral thesis, 2009)
The present PhD thesis is concerned with electron backscatter diffraction (EBSD) based in-situ observations of fine-scaled polycrystalline microstructures during thermomechanical processing in the scanning electron microscope ...
