Q 14.4: Mass spectrometry is ideally suited for analyzing pure compounds. However, when dealing with a mixture that contains several compounds, the compounds must first be separated from each other and then individually injected into the mass spectrometer to yield different spectra. This process has been greatly simplified by the advent of A gas chromatography - mass spectrometry (GC-MS) B C IR spectroscopy hydrogen deficiency index (HDI) D Electrospray ionization (ESI) E high resolution mass spectrometry
