Conclusions
-
1.
The influence of the ionizing voltage, temperature of the ionization chamber, and design of the filling system upon the relative intensities of the peaks in the mass spectra of phenyl- and methylthiohydantoins of amino acids was studied.
-
2.
In the mass spectra of most of the thiohydantoins, obtained on a system of introduction of the substance into the ion source of the mass spectrometer, the relative intensities of the peaks can be measured with an accuracy of ±1%.
