After a compound is introduced to the mass spectrometer, the sample is bombarded with a beam of high energy electrons. After this, ...Group of answer choicesThe sample forms a radical cation. This molecular ion has a mass-to-charge ratio identical to the molecular weight of the initial compound.The molecular ion is not detected by mass spectrometry.The molecular ion fragments into pieces, yielding other radical cations that are detected by mass spectrometry.The amount of energy absorbed by the beam of high energy electrons is detected and reported by the mass spectrometer.Both A and C.

In mass spectrometry, a sample's molecules are ionized in a vacuum and then exposed to a uniform electric field created by a high voltage plate in the acceleration chamber.  The electric field accelerates the ions until they arrive at the next section of the device, designated as the separation chamber.  In this section, the drifting ions are sorted by their mass-to-charge ratio (m/q).The separation chamber in a time-of-flight mass spectrometer (TOF-MS) is linear and has no electric or magnetic fields.  The ions travel at a constant velocity through the chamber until they reach the detector.  The time it takes for an ion to reach the detector depends on its m/q ratio.Figure 1  Time-of-flight mass spectrometerA magnetic sector mass spectrometer (MS-MS) has a curved separation chamber in which a magnetic field is applied.  The magnetic field exerts a centripetal force on drifting ions, bending their trajectories into curved paths.  The radius of the curvature depends on the ion's m/q.Figure 2  Magnetic sector mass spectrometerThe centripetal force F acting on a particle can be determined from its mass m, its velocity v, and the radius r of its curved path:𝐹=𝑚𝑣2𝑟Equation 1 Question 43Which of the following best describes the high voltage plate if it accelerates positive ions away from it?A.It is positively charged, and its electric field lines point away from it.B.It is positively charged, and its electric field lines point toward it.C.It is negatively charged, and its electric field lines point away from it.D.It is negatively charged, and its electric field lines point toward it.
