Analysis duration for a single sample does not exceed 1 min. Calibration curves were constructed, and the analytical characteristics of the method were determined using the “dilution in matrix” approach. The LC–MS/MS and APLPI methods exhibit comparable signal-to-noise ratios. The advantages of the APLPI method include its rapidity, retrospective analysis capability, and the requirement for only small sample volumes.
