Unformatted text preview: bundances in liver tissue. In this device, the sample is
ionized and the ions are accelerated from rest through a known potential difference. They then pass
through a small hole into a region with a uniform magnetic field perpendicular to the direction of the
ions. In the magnetic field region, the ions move until their velocity is reversed. At this point, it hits a
detector array. To determine an ion’s identity, you calculate the ion’s charge to mass ratio as a function
of the distance between where the ion enters the magnetic field and wh...
