Precision of fragmentation patterns in high-resolution mass spectrometry.
The effect of controlling the temperature of the ion source of a high-resolution mass spectrometer is to increase the confidence in mass spectral pattern coefficients of saturated molecules. Results are presented for both controlled and uncontrolled ion-source temperatures. Standard deviations have been calculated for selected summations of ion intensities and criteria have been suggested for maintaining meaningful analytical results in the study of petroleum distillates.
