Question:

Please answer the questions below.

a) In the mass spectrum for the compound shown, what is the m/z for the molecular ion?

b) Which cations are likely to form in an EIMS instrument during the fragmentation of the compound?

Mass Spectrometry

The three main components of any mass spectrometer includes

1. Ionizer

2. Analyzer

3. Detector

The role of the ionizer it to create gas phase ions that are analysed. This can be performed in a number of ways. Eelectron Ionization (EI) is a common technique, using high energy for fragmentation (70 eV).
