Exp3_2_03:	36:2	there are no MS/MS spectra
Exp3_2_05:	36:2	there are no MS/MS spectra
Exp3_5_02:	36:2	only 18:1/18:1 detected (stronger fragment)
Exp3_5_03:	36:2	only 18:1/18:1 detected
Exp3_5_05:	36:2	only 18:1/18:1 detected

PE:
36:2_Na		peak is always detected on the ms1 level, but there are hardly any spectra present;
		if there are spectra, surprisingly, the 18:1 fragment is close to noise, while 18:0 and 18:2
		show normal fragments -> the quantity is absolutely unusable
