Mass Spectrometry Can determine the molecular weight of a sample and some information about the structure A key part of a mass spectrometry is the need to create a charged species The most common method to create the charged species is electron impact ionization e⊙ H HH H H H 业● e⊙ H:C:C:C:H H:C:C·C:H 。。 HHH HH H e⊙ An electron is accelerated toward a gaseous sample of the compound under consideration Due to the high energy of the electron moving at high speed,an electron is expelled The sample thus is now positively charged,due to the loss of one electron, and is a radical/cation structureMass Spectrometry Can determine the molecular weight of a sample and some information about the structure A key part of a mass spectrometry is the need to create a charged species The most common method to create the charged species is electron impact ionization C C C H H H H H H H H C C C H H H H H H H H e e e An electron is accelerated toward a gaseous sample of the compound under consideration Due to the high energy of the electron moving at high speed, an electron is expelled The sample thus is now positively charged, due to the loss of one electron, and is a radical/cation structure
