Orbitrap technology was successfully applied for broad metabolite-based LC-high resolution (HR)-MS screening of drugs in clinical and forensic toxicology. This paper aims to elucidate whether this technology can also be used for a corresponding blood plasma screening after simple precipitation without or with consecutive on-line extraction using turbulent flow chromatography (TurboFlow). The analytes...
LC–high resolution (HR)-MS well established in proteomics has become more and more important in bioanalysis of small molecules over the last few years. Its high selectivity and specificity provide best prerequisites for its use in broad screening approaches. Therefore, Orbitrap technology was tested for developing a general metabolite-based LC–HR-MS/MS screening approach for urinalysis of drugs necessary...
