Doping control analysis of recombinant human erythropoietin, darbepoetin alfa and methoxy polyethylene glycol-epoetin beta in equine plasma by nano-liquid chromatography–tandem mass spectrometry
TLDR
A method for the detection and confirmation of rhEPO/DPO, as well as the newly released PEG-EPO, in equine plasma using nano-liquid chromatography–tandem mass spectrometry equipped with a nanospray ionisation source is presented.
Controlling the misuse of cobalt in horses.
Cobalt is a well-established inducer of hypoxia-like responses, which can cause gene modulation at the hypoxia inducible factor pathway to induce erythropoietin transcription. Cobalt salts are orally
Analyses of quaternary ammonium drugs in horse urine by capillary electrophoresis – mass spectrometry
TLDR
A direct comparison was made with existing liquid chromatography/mass spectrometry methods in the detection and confirmation of glycopyrrolate and ipratropium bromide in horse urine, where the two drugs could only be detected within the same CE‐MS run at 1 ng/mL in urine.

Doping control analysis of seven bioactive peptides in horse plasma by liquid chromatography–mass spectrometry
TLDR
This is the first identification of in vitro metabolites of all the studied peptides other than TB-500 in horses, and the applicability of this multi-analyte method was demonstrated.
