26. Mass spectrometry plays a central role in diverse areas of chemistry for the characterization of chemical species. Which of the following statements is INCORRECT?
(A) Mass spectrometry measures the mass-to-charge ratio (m/z) of ions rather than their absolute mass.
(B) High-resolution mass spectrometry allows the determination of elemental composition.
(C) Soft ionization techniques often produce intact molecular ions with minimal fragmentation.
(D) Isotopic patterns in mass spectra can be used to confirm molecular formulas.
(E) Electrospray ionization produces only singly charged ions regardless of molecular size.
