Multiple Choice
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.
