Spray-capillary coupled with MS for quantitative sample injection. (A) EICs of AngII (m/z = 523.77−523.80) were evaluated with different injection times; (B) Calibration curve was constructed as a function of injection time (N = 3 for each experiment condition); (C) The injection reproducibility was demonstrated here using three replicated injections with 60 s injection times using the EICs of AngII (m/z = 523.77−523.80).
