Analytic technique - mass spectrometry

Question 1

Mass spectrometry

Answer 1

• used to determine the structure of a molecule and if certain elements are present
• ions are formed by colliding a beam of electrons into a sample to loose an electron - now has a positive charge
• positive ions from the sample are detected by a magnetic field based on mass charge ration
• fragmentation occurs when the beam of electrons breaks a covalent bond in the parent molecule
• produces one part of a molecule that has a positive charge (can be detected) and one neutral part
