Standard:

Not detected:

01: 	13:0	seems to be removed by rules (peak has a stronger spectrum of something else at the beginning)
	14:0	there is only noise there
	18:0	there is only noise there
	
02: 	14:0	there is only noise there
	18:0	there is only noise there	

03:	13:0	there is only noise there
	14:0	there is only noise there
	18:0	there is only noise there
	18:1	removed by rules (MS1 algorithm integrated two peaks - first one shows a very strong PC content -> LPC_Na fragments are too weak)
	

Biological:
The Na rules are very unspecific,
because the spectra of the standards differ - some show quite a strong precursor,
while for others there is nearly no precursor present.
Consquently, there are many FPs and only one correct one is detected.
