Suppose you are concerned in a GC-MS lab, you injected a mixed calibration test that intervening six benzene sequence compounds (benzene, toluene, o-xylene, m-xylene, p-xylene, ethylbenzene) and indecent chlorobenzene sequence compounds (chlorobenzene; 1,2-dichlorobenzene; 1,3-dichlorobenzene; 1,4-dichlorobenzene). However, somehow you could not perceive all 10 peaks but observed a completion of singly seven peaks in the completion ion chromatogram (TIC). The GC-MS library exploration too involved that benzene is unctuous not shown in the chromatogram. In individualization to seven senior peaks, you too noticed a fine peak that does not competition any of the chemicals listed aloft. For each of these three observations, illustrate what could be the argue(s), and if there are any possible ways, how to unfold the collection and/or ameliorate the way.
