Liquid chromatography tandem mass spectrometry for plasma metadrenalines
Clinica Chimica Acta, 2019 Evidence is accumulating which may result in plasma free metadrenalines (PMets) becoming the preferred test for diagnosing phaeochromocytoma and paraganglioma. Moreover, increased availability and benefits over other analytical methods like liquid chromatography with electrochemical detection and immunoassay are causing liquid chromatography tandem ...

Liquid Chromatography Tandem Mass Spectrometry Quantification of 13C-Labeling in Sugars
Metabolites, 2020 Subcellular compartmentation has been challenging in plant 13C-metabolic flux analysis. Indeed, plant cells are highly compartmented: they contain vacuoles and plastids in addition to the regular organelles found in other eukaryotes.

Liquid Chromatography-Tandem Mass Spectrometry – Application in the Clinical Laboratory [PDF]
Clinical Chemistry and Laboratory Medicine, 2003 This review provides a concise survey of liquid chromatography-tandem mass spectrometry (LC-TMS) as an emerging technology in clinical chemistry. The combination of two mass spectrometers with an interposed collision cell characterizes LC-TMS as an analytical technology on its own and not just as a more specific detector for HPLC compared with ...
