• The figure shows the essentials of a mass spectrometer, which can be used to measure the mass of an ion; an ion of mass m (to be measured) and charge q is produced in source S. The initially stationary ion is accelerated by the electric field due to a potential difference V. The ion leaves S and enters a separator chamber in which a uniform magnetic field is perpendicular to the path of the ion. A wide detector lines...
10) Mass Spectrometer: (14 pts) A charged nucleus of mass m and charge q is accelerated through a constant potential V and enters a region of constant magnetic field B. The nucleus then undergoes circular motion before hitting a detector. 10) Mass Spectrometer: (14 pts) A charged nucleus of mass m and charge q is accelerated through a constant potential V and enters a region of constant magnetic field B.

Explain how a mass spectrometer is used to separate ions of different mass-to-charge (m/z) ratios by placing the statements in the order in which they occur. First step Gaseous ions are created in the ion source. The ions enter the vacuum chamber of the mass spectrometer A magnetic field is applied to the ions. The ions are deflected by the magnetic field. The velocity of the ions is increased as they pass through metal plates with a voltage applied to...
+V 0V Detector The picture above shows part of a mass spectrometer that can be used to measure molecular charge-to-mass ratios. A charged molecule (orange circle) is ionized and accelerated through an electric potential difference into a region with a uniform magnetic field. Here the magnetic field points out of the screen. The field makes the positively charged molecules undergo circular motion as shown. By adjusting the voltage difference between the plates, one can change the radius of curvature of...
Consider the mass spectrometer shown schematically in the figure below. The electric field between the plates of the velocity selector is 940 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.920 T. Calculate the radius r of the path for a singly charged ion with mass m = 2.30 ✕ 10−26 kg. ..... mm A singly charged positive ion has a mass of 2.60 ✕ 10−26 kg. After being accelerated through...

Problem 4 (25 points) The figure below shows a mass spectrometer, a device used to measure the masses of ions. Consider a positive ion of unknown mass m and charge q = 3.2 x 10-19 C. The ion is first accelerated from rest through a potential difference of magnitude 1v1 = 750 V inside a source. After leaving the source, it travels upward at constant speed and enters a region of uniform magnetic field B = 2.5 T directed out...
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....
Consider a mass spectrometer with a uniform 18T magnetic field. A gold ion with charge 1.602 x 10-19C and mass 3.27 x 10-2kg is shot into the the magnetic field and travels in a circular trajectory of radius 30.0cm How fast is the ion traveling? (a) 3.1 x 103 m (b) 9.9 x 105 m (c) 2.6 x 106 m (d) 1.2 x 107 m (e) 3 x 108 m
(Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio q/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As...
