Standard:

32:0	never detected in any sample (removed by istopic peak removal, since peak is overlapped by much stronger +2 isotope of PE 34:1)
34:0	not detected in samples 01 (+1 isotopic peak is noise only), 02 (+1 isotopic peak is stronger than +0) and 03 (covered by much stronger +2 isotope of PE 36:2)
34:1	never detected in any sample (removed by istopic peak removal, since peak is overlapped by much stronger +2 isotope of PE 36:2)
36:0	not detected in samples 01 (+1 isotopic peak is noise only), 02 (+0 peak is covered by noise) and 03 (+1 isotopic peak is noise only)
40:0	not detected in samples 01 (+0 peak is in too noisy region), 02 and 03 (+1 isotopic peak is covered by noise)
48:2	no ms2 in sample 03

PC_-CH3 is quite small and hardly discernable from PE_-H. There are some PE FPs
detectable for 34:0 and 34:1 when analyzed without PE.
In 12/27 cases the the species were identified. Spectra are present in
11/12 cases. In 11/11 cases, FAs were assigned, and in 11/11 the correct FA combination was detected.
No FP chains were assigned. In 9/9 cases, a position was assigned, and all positional
assignments were correct.


Biological:
Sometimes, there are FPs from PC_-CH3 which impair the retention time filtering - maybe RetentionTimePostProcessing=false
would be better for PC_-CH3, but it showed only in 2 out of 15 samples negative side effects.
