There are multiple ways to create ions for analysis via mass spectrometry. Understanding how the ions are created is essential in interpreting the mass spectrum produced. Two common methods of ionization are electron ionization and chemical ionization. Answer the following questions regarding these two types of ionization. Make sure to answer all three questions. Describe how ions are created via electron ionization. O Analyte molecules are bombarded with high energy electrons (usually 70 eV). allowing the molecules to absorb enough energy to ionize. O Analyte molecules are bombarded with protons that pull electrons away from the analyte molecules creating ions in the process A reagent gas is converted to reactive species by energetic electrons. These new reactrve species then donate a proton to the analyte molecules to produce the protonated molecule, ? Analyte molecules we heated with microwaves until they absorb sufficient energy to ionize. O Analyt molecules are ejected from the solution phase to the gas phase. During this process the analyte molecules lose an electron causing ionization. Describe chemical ionization O Analyte molecules we ejected from the solution phase to the gas phase During this process the analyte molecules lose an electron causing Ionization. A reagent gas is converted to reactive species by energetic electrons. These new reactive O species then donate a proton to the analyte molecules to produce the protonated molecule. MWH^+ OAnalyte molecules we bombarded with high energy electrons (70 eV), allowing the molecules to absorb enough energy to ionize O Analyte molecules are bombarded with protons that pull electrons away from the analyte molecules creating ions the process O Maisie molecules are heeled with microwaves until they absorb sufficient energy to Ionize Which typo of ionization would you expect to produce the most fragmentation? 0 chemical ionization O electron Ionization O they would produce the same amount of Ionization

Explanation / Answer

ionic ionization- first option is correct

Chemical ionization - second option is correct

Ionic ionization will produce more fragmentation due to higher ebergy as compared to chemical ionization
