Magnesium interference and different efficiencies of diastereoisomeric cluster formation in phenylalanine enantiomeric discrimination by the kinetic method
Original language description
The kinetic method has been applied for determination of D-Phe/L-Phe enantiomeric ratio. Discrimination of enantiomers was inferred from product ion mass spectra of trimeric cluster ions containing the analyte (L,D-Phe), Cu2+ as a central metal and L-Trpas a chiral reference ligand. Unsatisfactory quantitative results achieved on an ion trap were rationalized by high-resolution mass spectrometry. The formation of Mg2+-containing cluster isobaric to trimeric cluster [Cu(L-Trp)(2)Phe](+) was observed. Interference like this was identified as a possible reason for deterioration of quantitative low-resolution mass spectrometric analyses of real-world samples based on the kinetic method. Cation-exchanger was used for easy removal of magnesium from a sampleand improvement of quantitation.
