High resolution mass spectrometry: This method allows
Masses are generally not whole number integers, for example 1 proton =
One
All atoms other than
Nominal mass: The nominal mass for an element is the mass number of it is most abundant naturally occurring stable isotope and for an ion or given molecule the nominal mass is the sum of the nominal masses of the constituent atoms.
Example: The exact mass of the most abundant isotopes of each element
For example hydrogen

- sketch an approximate mass spectrum of ethane ( C2H6)arrow_forwardUsing the rule of 13, what is a possible formula for M=113 (100%) on a mass spectrum? all of the above are possible molecular formulas CH130 CH15Narrow_forwardA low-resolution mass spectrum of the neurotransmitter dopamine gave a molecular ion at m/z = 153. Two possible molecular formulas for this molecular ion are C8H11NO2 and C7H11N3O. A high-resolution mass spectrum provided an exact mass at 153.0680. Which of the possible molecular formulas is the correct one?arrow_forward
- Briefly explain the principles of APCI mass spectrometryarrow_forwardHalogenated compounds are particularly easy to identify by their mass spectra because both chlorine and bromine occur naturally as mixtures of two abundant isotopes. Recall that chlorine occurs as 35Cl (75.8%) and 37Cl (24.2%); and bromine occurs as 79Br (50.7%) and 81Br (49.3%). At what masses do the molecular ions occur for the following formulas? What are the relative percentages of each molecular ion? (a) Bromomethane, CH3Br (b) 1-Chlorohexane, C6H13Clarrow_forwardMass spectrometry is often used to both identify and quantify compounds. What is different between mass spectra with changing concentrations of a compound? How would you design a method (i.e. what would you need) to both identify and quantify a compound using mass spectrometry?arrow_forward

- Bromine has two naturally occuring isotopes, Br-79 and Br-81, approximately 50% of each. Bromomethane will contain approximately 50% Br-79 and 50% Br-81. The mass spectrum peak for methane containing Br-79 will be referred to as the M+ (molecular ion) peak, and the peak for Br-81 will be called the M+2 peak, as Br-81 weighs two more amu than Br-79. What will be the locations of the two bromomethane peaks on the mass spectrum and what will be the approximate ratio of their heights?arrow_forwardWhat is responsible for the small peak at m/z = 17 in the mass spectrum of CH4?arrow_forwardWhat mass range or molecular mass range can be detected using GC-MS?arrow_forward
