Extraction of Mass Spectra

One of the great strengths of mass spectrometry is the provision of direct information about an eluting component. The careful extraction of the substance-specific signals from the chromatogram is critical for reliable identity determination. For identification or confirmation of individual GC peaks, recording mass spectra which are as complete as possible is an important basic prerequisite. 

If Other ions are included in this first mass analysis, it can be concluded that the fragments belong together from their common maximizing masses behaviour (Biller and Biemann, 1974). 

In the subtraction of mass spectra, it should generally be noted that in certain cases primary substance signals can also be reduced. In these cases, it is necessary to choose another background area. If changes in the substance spectrum cannot
