Question

Consider the following statements as they apply to mass spectrometry. Decide if each is true or false.

It is possible to get a mass spectrum of large analytes like polymers and biomolecules because of the development of ionization techniques such as MALDI and FAB.

For a particular analyte, the mass spectrum obtained is highly dependent upon the ionization technique used.

Though a gas chromatograph (GC) is a common way to introduce a sample into a mass spectrometer, a liquid chromatograph (LC) is never used for this purpose.

A mass spectrometer is an instrument that produces ions and separates them according to their mass to charge ratios, m/z.

The nominal mass of an ion is calculated by summing up the atomic masses of the most abundant isotopes.
