The full mass scan was acquired from m/z 350 to 1550 with resolution 120,000 at a target of 2e5 ions, and the MS/MS spectra were obtained in a data dependent acquisition in the top speed mode with higher-energy collision dissociation (target 5e4 ions, max ion injection time 100 ms, isolation window 1.6 m/z , normalized collision energy 25%)
L-carnitine is a derivative of the essential amino acids found in proteins
Regardless, most research applications utilize the injected version, and this is also the form that is most often used in both research and clinical settings
