Underivatized polyamine analysis in plant samples by ion pair LC coupled with electrospray tandem mass spectrometry
Polyamines are key regulators of cell development and many plant responses to environmental challenges, however, their functions still remain unclear in complex interactions with other hormones and in biotic or abiotic ...
Investigation of pesticide metabolites in food and water by LC-TOF-MS
We illustrate the potential of liquid chromatography with (quadrupole) time-of-flight mass spectrometry [LC-(Q)TOF-MS] in investigating the presence of pesticide metabolites in food and water samples. The higher polarity ...
Detection and characterization of anabolic steroids in doping analysis by LC-MS
The detection of target anabolic steroids in doping analysis has generally been performed by gas chromatography combined with mass spectrometry (GC-MS). However, liquid chromatography combined with tandem mass spectrometry ...
Gas chromatography-mass spectrometric determination of polybrominated diphenyl ethers in complex fatty matrices from aquaculture activities
Gas chromatography coupled to mass spectrometry in negative chemical ionization mode (GC-(NCI)MS) has been applied to the quantification and reliable identification of polybrominated diphenyl ethers (PBDEs) in animal and ...
Direct quantification of steroid glucuronides in human urine by liquid chromatography-electrospray tandem mass spectrometry
A method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the direct quantification of glucuronides of testosterone (TG), epitestosterone (EPG), androsterone (AG) and etiocholanolone (ETG) has been ...
