Comprehensive comparison of liquid chromatography selectivity as provided by two types of liquid chromatography detectors (high resolution mass spectrometry and tandem mass spectrometry): “Where is the crossover point?”
TL;DR: The data indicated that the selectivity of LC-HRMS exceeds LC-MS/MS, if high resolution mass spectrometry (HRMS) data is recorded with a resolution of 50,000 full width at half maximum (FWHM) and a corresponding mass window.

Development of an improved high resolution mass spectrometry based multi-residue method for veterinary drugs in various food matrices.
TL;DR: Significantly better performance parameters were obtained when comparing the new method with the older, TOF based method, attributed to the higher resolution (50,000 versus 12,000 FWHM) and the superior mass stability of the of the Orbitrap over the previously utilized TOF instrument.

Ultra-performance liquid chromatography coupled to time of flight mass spectrometry (UPLC-TOF): a novel tool for multiresidue screening of veterinary drugs in urine.
TL;DR: The usefulness of metabolites as additional confirmation criteria for positive findings is discussed and a revisiting of the identification point system is suggested in the light of additional resolution, as provided by the TOF and the UPLC technology.

Determination of aminoglycoside residues by liquid chromatography and tandem mass spectrometry in a variety of matrices
TL;DR: A quantitative LC-MS/MS method was developed for the determination of 13 commonly used aminoglycoside antibiotics in meat (pork muscle, fish, and veal livers and kidneys) that is sufficiently sensitive and highly selective and uses a simple clean-up procedure based on a strong cation-exchange solid-phase cartridge.

Quantitative and confirmative performance of liquid chromatography coupled to high‐resolution mass spectrometry compared to tandem mass spectrometry
TL;DR: Evaluated was a new extraction and clean-up protocol which was developed to cover more than 100 different veterinary drugs at trace levels in a number of animal tissues and honey matrices, and confirmed that confirmation of analytes present at low levels is superior when performed by MS/MS.
