A key element in data interpretation is to identify any warning flags. Warning flags can help a chemist differentiate good data from bad data.
For an unknown compound, the TOF-ESI+ mass spectrum below shows the expanded region around four isotope clusters at m/z 300.336 ([M+H]+), 322.307 ([M+Na]+), 599.672 ([2M+H]+) and 621.611 ([2M+Na]+).
Are the intensities of the 13C isotope any indication of a problem with the data?
