Mass spectrometry (MS) is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. Clinical applications of mass spectrometry continue to expand, and mass spectrometry is now being used in almost all areas of laboratory medicine. WORKED SOLUTION Mass spectrum: M+ gives MW = 164 g/mol , no isotope pattern for Cl or Br. CHM 202 - Mass Spectrometry Problems (with some IR) 1. The actual spectra may be examined by clicking one of the designated buttons. Select a problem by checking a radio button, and then click the "Show the Selected Problem" button. Mass spectrometry (MS) is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. Show your work. cm cm . The best approach for spectroscopy problems is the following steps: Calculate the degree of unsaturation to limit the number of possible structures. Milman, I.K.
