Which of the following is INCORRECT for quantitative or qualitative analysis with gas chromatography?
A)The confirmation ion collected by a mass spectrometer is used to quantify a peak.
B)Selected ion monitoring identifies a peak by monitoring the m/z characteristic for the compound.
C)Internal standards quantify compounds by adding a known amount of compound to the sample and calculating the concentration from peak areas for the compound and internal standard,and the response factor for the two compounds.
D)Spiking identifies a peak by a known compound to the unknown.If the peak area increases,the peak has been identified.
E)Linear response for concentration and detector response is required for quantitative analysis.

The confirmation ion collected by a mass spectrometer is typically used for the qualitative identification of a compound, not for quantification. Quantification is usually done using the most abundant ion (quantifier ion) or a selected ion that provides the best sensitivity and specificity for the compound of interest.
